High-Resolution Ultrastructural Imaging
Explore Biological Specimens with Electron Microscopy
You are pushing for the highest resolution that only electron microscopy can provide. You may be hunting for a 3D understanding of small structures buried deep in your samples. Or you want to gain a better understanding of ultrastructure in its native state. ZEISS electron microscopy offers solutions for high resolution, structural imaging of biological specimens, supporting cell or cancer research, microbiology or virology, immunology, neuroscience, embryology, or developmental biology to plant sciences.
High-Resolution Imaging for Ultrastructural Information
Achieve high-contrast imaging with resolution down to sub-nanometer with field emission scanning electron microscopes, including the ZEISS GeminiSEM family and ZEISS Sigma family. Experience TEM-like imaging with your FE-SEM for precise visualization of intracellular structures, organelles and viruses in your ultrathin sections of resin-embedded samples.
High-Resolution 3D Imaging Without Prior Sectioning
High resolution 3D imaging provides detailed structural investigations of single cells to large tissues, including connectomics studies, to entire organisms for developmental biology research.
Use integrated block face imaging inside your FE-SEM with ZEISS 3View to slice your sample block directly in the chamber and image after each slice. This method allows for investigation of larger 3D volumes – up to several million cubic micrometers – with Z-thickness slices down to 15 nm.
Or use focused ion beam milling with ZEISS Crossbeam and achieve Z resolutions of down to 3 nm for ultra high-resolution 3D imaging using FIB-SEM tomography.
Scanning Electron Microscopy at Record Speed for Large Tissue Sections
ZEISS has developed a novel multi-beam SEM technology for imaging large sample areas, the ZEISS MultiSEM family. In partnership with sample preparation robots, MultiSEM dramatically speeds up the acquisition of 3D ultraresolution data through array tomography. Mapping larger (1 mm³) brain tissue, such as for connectomics analyses, or other tissue volumes at high resolution is now within reach.
Investigate Structure and Function at Near Native State with Cryo FE-SEM
Native morphology can only be observed when you freeze your sample instead of using chemical fixatives. ZEISS field emission SEMs and FIB-SEMs support cryo workflows and can image your delicate samples with outstanding performances at low voltages. ZEISS has also developed a seamless Correlative Cryo Workflow which connects widefield, laser scanning and focused ion beam scanning electron microscopy in a seamless and easy-to-use procedure.
Get unsurpassed surface morphology imaging on a wide range of samples with an SEM, such as ZEISS EVO, or FE-SEM, such as ZEISS Sigma – without coating or sophisticated sample preparation. Image uncoated insects or bone material, wet specimens, grid sections, resin embedded block faces or vitrified samples. Use variable pressure to control environmental conditions in the chamber and image samples under low vacuum conditions.
