  • Tissue fixation, dehydration and embedding in epoxy resin

    Epoxy embedding serves a dual purpose - it fixates and preserves the structural integrity of biological material of interest without drastically altering the sample and encloses the material in a solid, hard environment that is suitable for cutting semi-thin and thin sections for TEM viewing. Fixation is done using a 2.5% glutaraldehide solution and a 1% osmium tetraoxide solution, the latter also used in tandem with a 2% uranilacetate solution for negative staining. Dehydration is performed by immersing the material in graduated solutions of distilled water and ethanol with a subsequent immersion in pure propylene oxide to fully substitute the materials’ water for a liquid miscible with the epoxy resin of the embedding medium. The tissue is then sent through a mixture of epoxy and acetone, and then through pure epoxy to substitute any liquid for resin components. The prepared tissue is placed into plastic capsules, which are filed with epoxy, and cured for up to 4 days in an incubator (60 oC) until ready for sectioning.

  • Ultra-high resolution field emission scanning electron microscopy (Nova NanoSEM™ 650) imaging

    Characterization of solid material surface structure and morphology. Field emission scanning electron microscopy imaging is performed at high and ultra-high magnifications. From the obtained high-resolution images (Depending on the material being imaged, the resolution of the system is about 2nm.) it is possible to precisely measure very small features and objects (surface or cross-sectioned). This service will include FESEM images of samples with the option for sputter coating and interpretation of results on request. Advanced sample preparation is also offered for an additional fee

  • Ultra-high resolution scanning electron microscopy (Nova NanoSEM™ 650) chemical analysis obtained with Energy Dispersive X-ray spectroscopy (EDS) line analysis

    The SEM/EDS is capable to perform line scan analysis of selected locations on the sample. EDS is analytical technique used for the elemental analysis or chemical characterization of a sample. EDS spectra can be collected across the specimen’s image area in a line. Weight and atomic percentages are calculated for each identified element. The line scans provide additional flexibility to customize the number of measurement points in a line.

  • Ultra-high resolution scanning electron microscopy (Nova NanoSEM™ 650) chemical analysis obtained with Energy Dispersive X-ray spectroscopy (EDS) point analysis

    The SEM/EDS is capable to perform analysis of selected point location on the sample. EDS is analytical technique used for the elemental analysis or chemical characterization of a sample. EDS spectra can be collected across the specimen’s image area, including individual points, multiple points, selected areas or freehand draw. Weight and atomic percentages are calculated for each identified element.
