  • How scanning electron microscopy is used for cosmetics research and development

    Since ancient Egyptian times, cosmetic products have been used to enhance the human appearance. Research around cosmetics therefore deals not only with the development of new substances and the analysis and enhancement of existing ones, but also with the interaction of components with tissue. In this short blog, we introduce you to three examples that show the link between research within the cosmetic industry and scanning electron microscopy (SEM).

    Investigating the toxicity of copper oxide nanomaterials on different epithelial cells

    The use of nanoparticles in cosmetics is quite widely discussed as potential toxicity discussions are ongoing. In a study of Ude et al., the toxicity of copper oxide nanomaterials on different epithelial cells is investigated.[1]

    A huge variety of nanomaterials are available that vary in size, composition, surface area, charge, shape, and solubility. All these factors influence the biological response to the nanomaterials.

    Metallic nanomaterials such as copper oxide (CuO) particles can be soluble and due to this might be toxic via particle effects or ion-mediated effects. Ingestion of copper oxide nanomaterials by humans is most likely to occur accidentally and very little is known so far about the potential risks.

    Ude et al. choose the Caco-2 cell line to investigate the potential effect of these nanomaterials in addition to using SEM on cell culture material. Their study clearly demonstrates that the impact of CuO nanomaterials is comparable to studies already performed on copper sulfate (CuSO4) nanomaterials.

    SEM imaging confirmed a toxicity of CuO and CuSO4 nanomaterials on Caco-2 cell monolayer integrity. This is an indication that due to tight junction dysfunction, substances such as chemicals and pathogens could potentially be transported across the intestinal barrier.
    Researching the impact of titanium dioxide nanoparticles on E. coli.

    Fig 1: SEM image of deodorant. Cosmetics consist of very complex components and often contain particles.

    Still on the topic of nanoparticles, but with a different model system, Planchon et al. carried out a study. [2] The research was focused on the impact of titanium dioxide nanoparticles on Escherichia coli (E. coli). As reported previously, E. coli shows a toxic reaction from 10ppm onwards, but it was also stated that parts of the bacterial population are able to adapt and survive.

    SEM studies show some bacteria being fully covered in titanium dioxide particles, while the major part remains free from nanoparticles. This heterogeneity leads to differences in proteome and metabolome. To be able to deal with biological variety, the study therefore suggests analysing large samples to minimise the impact of unwanted variance.

    The Planchon et al. study revealed that exposing E. coli to titanium dioxide nanoparticles resulted in heterogeneous bacterial responses. One part of the population is able to adapt to the stress and temporarily survives, while the other part cannot adapt and dies. The study’s attempt at combining proteomics and metabolomics might offer a breakthrough in studying the effect of the nanoparticles as it offers a more precise evaluation of toxicity.

    Examining the characterisation of dentifrices

    A very different study by Pinto et al. aimed to characterise dentifrices, as they are a good source for fluorides.[3] This is because formulations have been improved to enhance therapeutic properties by incorporating, for example, triclosan, potassium nitrate or strontium chloride.

    The goal of the research team was to characterise 12 dentifrices via SEM and EDX analysis. To enable a SEM analysis the dentifrices were reduced to ashes at 650°C and then imaged and analysed by EDX. The study concluded that due to the many components included in dentifrices, each patient should have an individual evaluation to best understand their needs.

  • Scanning electron microscopy and pharmaceutical research topics

    Pharmaceutical research and questions linked to drug development and applications is a very diverse topic. Also the instrumentation involved in research and development is just as diverse. In this blog we will focus on the use of scanning electron microscopy (SEM) in three different research topics.

    Understanding nano-bio interfaces
    The diversity of technologies used within pharmaceutical research, with an emphasis on the importance of microscopy techniques, is summed up in the review of Jin et al.[1]. Nowadays, microscopic observations play a key role in nanotechnology research with applications in pharmaceutical sciences.

    Multi-scale observations are especially needed to understand nano-bio interfaces, where a wide range of phenomena are to be described. The benefit described in the SEM section is fewer artefacts, compared to atomic force microscopy, since no physical interaction with the sample is needed to gain images.

    In general, nano-bio interfaces can be understood as cell – nanotube or tissue – nanoparticle interaction and potential morphological changes occurring due to nanomaterials in cells and tissues. Observations of these interfaces enable future developments in pharmaceutical applications.

    Observing microvesicles
    Extracellular microvesicles (EMVs) are membranous nano-sized cellular organelles naturally released by cells in vitro and in living organisms. Microvesicles can be found in various human body fluids: blood plasma, urine, breast milk, and amniotic fluid.

    As they have been observed to carry functional proteins, RNA molecules and antigens, they can be understood as a novel way of cell-cell communication. Previous research work has shown that altered microvesicles gained from bovine milk containing mRNA and miRNA can be transferred to immune cells to potentially alter immune cell function.

    In the study described by Maburutse et al., various preparation techniques for microvesicles were compared [2]. The microvesicles were observed after preparation via SEM via secondary electron detection. To enable this observation to take place, the vesicles were fixed with paraformaldehyde, and air dried. The various preparation techniques resulted in a unique set of characteristics in the microvesicles.

     Optimising solid self-nano-emulsifying drug delivery

    As a final example, we can also consider drug delivery. Self-nano-emulsifying drug-delivery systems (SNEDDS) have emerged as effective delivery systems due to the development of enhanced bioavailability of lipophilic drugs. Dash et al. describe in a study an optimisation of solid self-nano-emulsifying drug delivery for enhanced solubility and dissolution [3].

    Involving scanning electron microscopy, it was concluded that there was no evidence of drug precipitation on the surface of solid SNEDDS. This will lead to a better future application, although investigations on animal/human models are needed.

    More on SEM in pharmaceutical research
    The three previous examples should provide a better understanding of the power and potential of SEM within pharmaceutical research. In short, the successful application of SEM fuels the development of more powerful, better-performing drugs.

  • SEM analysis of PVDF-HFP nanofibres for the fabrication of energy harvesters

    Nowadays, energy harvesting is seeing an increasing interest from the research community, a fact that is confirmed by the rising number of publications. Energy harvesting has a wide range of applications, ranging from portable electronics, such as wristbands, to implanted medical devices like pacemakers. In this field, researchers are focusing their attention on the development of new energy harvesters that satisfy strict requirements: they need to be light and small, but also cheap and highly portable. In this blog, we discuss the fabrication of energy harvesters made from PVDF-HFP nanofibers on PDMS and SF substrates. We investigate how these energy harvesters are characterised and what the role of SEM is in this study.

    Piezoelectric Energy Harvesting
    The increasing demand for innovative devices, such as embedded sensors in sportswear or smart watches, is drawing attention to energy harvesting. Energy harvesters have the capacity to convert external energy, which can be derived for instance from solar power or thermal energy, into electrical energy that can be used to power small electronic devices or wireless sensor nodes. Energy harvesters need to be small, light, inexpensive, portable, flexible and, in some cases, also biocompatible.

    One of the most common types of energy harvesters employs piezoelectric materials, which convert mechanical strain (for example human motion or acoustic noise) into electric current or voltage. A commonly-used piezoelectric material for energy harvesting applications is polyvinylidene fluoride (PVDF), which offers a good electro-mechanical coupling factor and is biocompatible, light and flexible.

    In a recent study, polyvinylidene fluoride-co-hexafluoropropylene (PVDF-HFP) nanofibers were investigated as suitable candidates for energy harvesters (R. Najjar et al., Polymers 2017, 9, 479). The performance of the nanofibers was characterized in combination with two different substrates, namely polydimethylsiloxane (PDMS) and silk fibroins (SF).

    The first is a type of synthetic polymer, while the second is a natural protein that provides better biocompatibility and more favourable sustainability. The characterisation of the performance of energy harvesters includes the analysis of the morphology, the mechanical properties, and the mechanical-electrical measurements.

    Characterisation of PDMS and silk substrates through SEM analysis
    A scanning electron microscope was employed for the analysis of the morphology of PDMS and silk films. For this analysis, two types of silk fibroin films were investigated: pure silk fibroin and silk fibroin with 20% glycerol content.

    Because silk fibroins tend to become stiff and brittle over time, glycerol is added to the silk fibroin to make it more flexible. 20% is the optimum glycerol content for increasing the softness of the silk film, without the film disassembling in water.

    Fig 1. shows -SEM images of the surface of pure silk fibroin (A-C), silk fibroin with glycerol (D-F) and PDMS films (G-I), illustrating the surface microstructures and morphology. The cross-sections are shown in Figure 1, (J-L) for pure silk fibroin, (M_O) for silk fibroin with glycerol and (P-R) for PDMS films.

    All three materials show continuous and homogeneous structures without voids. The rough cross-sections indicate the tenacity fracture of the films that are related to strong mechanical properties.

    Fig. 1: SEM images showing the surface morphology of different types of pure silk fibroin (A-C), silk fibroin with 20% glycerol content (D-F) and PDMS films (G-I) plus SEM images showing the cross-sections of pure silk fibroin (J-L), silk fibroin with 20% glycerol content (M-O) and PDMS films (P-R).

    The study of the mechanical properties of the three types of film is also of utmost importance. Fig. 2 shows the stress-strain curves of the three materials. The PDMS (blue curve) is mostly elastic with a linear stress-strain curve until the fracture, showing a maximum stretch of more than 400% its total length, whereas the pure silk fibroin (pink curve) is stiffer and has lower yield point than PDMS.

    Fig 2: Stress-strain curve of PDMS and two types of silk fibroin films.

    The data from the measurements on silk fibroin prove that this material can survive larger forces and greater elongation, although it is stiffer than PDMS.

    SEM analysis of PVDF nanofibres

    The PDVF-HFP nanofibres were fabricated using the electrospinning process. Two different types of fibres were produced: random nanofibres and aligned and stretched nanofibres. Fig.3 shows SEM images of the two types of nanofibres (A and B).

    From these images the fibres diameter and orientation can be measured. In Fig. 3, the diameter distribution for random and aligned fibres is shown (graphs C and D respectively). In the first case, the diameter varies between 600nm to 1600nm, while for aligned fibres it ranges from 300nm to 700nm.

    The orientation distribution (shown in graphs E and F) shows that the random fibres have a larger range of orientation (from -50° to +50°), while the aligned fibres have orientation with one large peak around 0°.

    Finally, the energy harvesting measurement was performed. Fig. 4 shows the voltage generated from PVDF-HFP random (A) and aligned (B) nanofibres on a PDMS substrate. The voltage generated from the stretched and aligned nanofibres is more than 12 times that of the electrospun random nanofibres.

    Fig. 4: Electrical output of OVDF-HFP nanofibres on PDMS substrates, for random nanofibres (A) and aligned nanofibres (B).

    The electro-mechanical characterisation was important in demonstrating that the aligned PVDF-HFP nanofibres have higher piezoresistivity and are therefore more suitable for energy harvesting applications. The SEM revealed to be a powerful instrument to analyse the morphology of the nanofibres and to measure the fibre diameter and orientation.

    From that, stretched nanofibres were shown to be better aligned with a more precise diameter control. They also outperformed the random nanofibres in the energy harvesting measurement by more than 10 times.

  • How SEM helps perform automated quality control on phosphate coatings

    We are surrounded by products that, for either decorative or functional purposes, are covered with coatings; from paintings and lacquers, to adhesive or protective coatings, optical, catalytic or insulating coatings. Of all these coatings, conversion phosphate coatings play an important role, especially in the automotive industry: they are used for corrosion resistance and lubricity. Since these coatings are used for critical parts, the coating process must undergo thorough quality checks. These checks consist of the analysis of the morphology of the coating as well as the percentage of coverage. In this blog, we describe and analyse how automated tools combined with SEMs can be helpful in quality checking phosphate coatings.

    Conversion phosphate coatings
    Coatings are not only used as a decorative feature, such as paint finishes or lacquers; most of the time have a functional purpose. Coatings can:

    • Serve as an adhesive,
    • Have optical, electrical or magnetic properties,
    • Be catalytic or light sensitive, such as those used to make photographic film.

    One of the biggest categories is that of protective coatings, ranging from insulation to waterproof and wear resistant to anti-corrosion. Coatings can be applied through chemical vapour deposition, physical vapour deposition, spraying, or chemical and electrochemical techniques, such as electroplating.

    Within this wide range of functionalities, materials and coating techniques, we focus our attention on conversion phosphate coatings. These are typically used in the automotive industry and serve as a protection layer on steel parts, preventing corrosion and providing lubricity. The main types of coatings are manganese, iron and zinc. The coating is applied by immersing the part in a bath containing a phosphoric acid, which causes the growth of a crystalline zinc, manganese or iron phosphate layer.

    Because of the critical use of the coated parts, the coating process must undergo thorough quality checks to ensure the performance of the coating. The quality check consists of the analysis of the coating morphology and the percentage of coverage. One way to carry out this analysis is by using a scanning electron microscope (SEM).

    How SEM helps perform quality control inspections on coating processes
    SEM is an ideal choice for quality checking of conversion coatings and for the analysis of the crystal morphology. Moreover, imaging with the BSE detector is the most suitable technique to analyse the coverage of the coated sample because of the difference in atomic number between the phosphate coating and the steel.

    Since steel is an alloy of iron, and therefore has a higher atomic number than the phosphate coating, it will appear brighter in the back scattered image. Fig.1 shows a BSE image overlaid with the coloured EDX map, where the yellow areas consist of iron and the light blue refers to zinc. The brighter areas of the BSE images overlay with the yellow, demonstrating the effectiveness of using these images for the measurement of coating coverage.

    Fig. 1: SEM image in backscatter mode of a steel sample covered with zinc phosphate coating overlaid with a coloured EDX map, showing the coated (yellow-iron) areas and the coating (light blue-zinc)

    Moreover, at the same time, BSE images also reveal the crystal structure of the coating, enabling the coating morphology to be analysed. Fig. 2 shows an SEM image of the crystal structure of zinc phosphate coatings.

    Fig. 2: SEM images in backscatter mode of asample covered with zinc phosphate coating, showing the different morphology of the crystal structure.

    Why automated quality control is key
    In quality control processes, it is ideal to have a system that enables the user to get fast results and avoid long downtime on the production line. In most cases, the analysis of coated samples is done in a laboratory that is located far from the production line, causing unwanted delays in instances of negative feedback. Having a fast and reliable way to check the quality of phosphate on site is important. Desktop SEMs are the ideal choice in this case, having a small footprint and being easy to use.

    However, this may be not sufficient. An automated tool for quality checking that does not require a dedicated and experienced user gives more advantages in terms of time saving and the reliability of the results. The Phenom Programming Interface (PPI) is the right platform to implement an automated tool for quality checks.

    Fig. 3 shows the process flow of the automated tool designed for the quality checking of the coating coverage. It enables the user to scan a large area of the sample by collecting a set of BSEs images at low magnification and saving them in a selected folder.

    These images are then automatically analysed by applying a threshold on the grey level, effectively separating the coating (appears darker) and the uncovered steel (appears brighter). The average coverage percentage and the statistics of the measurement are then saved in a report that the user can print out later. It is also possible to load a set of images, select the correct threshold, do the analysis, and generate the report.

  • How scanning electron microscopy fuels biomedical research

    Biomedical research is a wide field. It describes an area of science devoted to the study of the processes of life, the prevention and treatment of diseases, and the genetic and environmental factors related to diseases and health. And since the field is so diverse, its range of investigation equipment is too. Scanning electron microscopy (SEM) is one of those types of equipment, and is used to describe tissue or organ structures to gain insights into possible alterations and diseases. To show the variety of topics explored with a SEM — demonstrating its power and vast range of applications — this blog will introduce you to three scientific studies.

    Revealing variations of the human cochlea
    The human cochlea appears to have variations, as proven with images by Rask-Andersen et al.[1]. These SEM images reveal the anatomical variations to raise awareness of them and their impact on cochlear implantation.

    The researchers point out that studies about the fine structure of the human cochlea may provide a better understanding of the intracochlear tissue interacting with an electrode during insertion and electric stimulation.

    To enable an observation with SEM, the cochlea was, after decalcification, divided mid-modiolarly using a razor blade. The organ of Corti with stereocilia tufts, as well as various hair cells and further structures, could be shown nicely after the preparation. In addition, possible trauma sites for cochlear implantation were analysed in further detail.

    Investigating the possibility of suppressing post-operative intimal hyperplasia
    Endothelial injury is considered to be the first step towards post-operative hyperplasia; an increase in the growth of organic tissue. Hyperplasia is seen to be the most common cause of vein graft occlusion.

    In their SEM study, Yamamurra et al. describe the possibility of suppressing post-operative intimal hyperplasia.[2] To be able to observe the impact of a free radical scavenger, edaravone, vein grafts were prefixed in glutaraldehyde and postfixed in osmium tetroxide. After critical point drying and sputter coating, the vein crafts were imaged and analyzed.

    The research team showed that the endothelial cells in unoperated veins had a cobblestone-like appearance. Comparing this to samples after a 1-hour bypass, the endothelial cells in the saline group showed a comb-like structure and the adherence of monocytes, while in the edaravone group the cobblestone-like structure remained and far fewer monocytes were observed. The team therefore concluded that edaravone might not only suppress hyperplasia, but also atherosclerosis.

    Figure 2: The fragile structure of the fenestrated bony columns is presented in (d,e). Reprint from Rask-Andersen et al.

    Reviewing ECM with SEM
    As a third and final example, we highlight the review on the ocular corneal extracellular matrix (ECM) by Quantock et al.[3] Electron optical imaging has already contributed to the research of ocular ECM for more than 60 years, and has found its place in describing fine structural anatomy and tissue changes in pathological conditions since the 1970s.

    While SEM has initially been employed in ocular matrix research along with studies of cell and lamellar organization, the development of FIB-SEM (focused ion beam) has taken it to a new level. As a result, it is now possible to image three-dimensional micro-anatomy.

    With these three examples we hope to have offered you a glimpse into how SEM is an invaluable research tool in biomedical topics, covering a vast range of applications, and fueling numerous future developments.

  • Baumer expands the successful CX and EX camera series with ten new models

    Up to 20 megapixel in 29 x 29 mm design for cost-oriented applications: CX and EX series add ten new models with rolling shutter sensors

    10 new models with rolling shutter sensors were added to the successful CX and EX Baumer camera series which now offers resolutions with 20 and 10 megapixel, respectively.

    Baumer expands the successful CX and EX camera series with ten new models featuring rolling shutter CMOS sensors by ON Semiconductor and Sony, including sensors from the STARVIS series. With resolutions of 5, 10, 12 and 20 megapixel, these sensors deliver low noise, low heat generation and an excellent price-performance ratio. Hence, these new models are the ideal choice for cost-sensitive applications that require low-price cameras with high resolution and image quality comparable to a global shutter sensor, reducing system cost. Thanks to their Global Reset function, which exposes all pixels simultaneously, even fast-moving objects are clearly captured at high image quality without the distortion seen with rolling shutter effects. First models are expected to go into production the 2nd quarter of 2018.

    The small CX and EX series USB 3.0 and GigE cameras include the latest rolling and global shutter CMOS sensors with up to 20 megapixel resolution and the uniform form factor of 29 x 29 mm. Users save time and money in realising multi-faceted applications with individual demands on resolution, interface or functional range thanks to consistent mechanical, electrical and software integration. Furthermore, the small square housing with sided M3 mounts is easily installed with maximum flexibility even in tight spaces.

    The CX series offers more than 80 models, including IP 65/67-rated cameras with an operating temperature range from -40 °C to 70 °C, exposure times from 1 µs to 60 s and frame rates of up to 1000 fps using a ROI (Region of Interest). Resolutions from VGA up to 20 megapixels and outstanding image quality make the versatile CX series an ideal choice for cross-industry applications with the highest demands on image detail accuracy and throughput.

    Focusing on the essential such as standard-compliant basic functions and CS mounts, the EX series offers Baumer quality at a small price. With resolutions of up to 10 megapixel and a robust metal housing, these are the cameras to choose for the most common applications in industrial image processing.
