Electron microscopes, including transmission electron microscopes (TEM) and scanning electron microscopes (SEM), are widely utilized to gain detailed structural information about biological samples or non-living materials. Ultramicrotomy is the preferred technique for producing ultrathin sections, less than 100 nm thick for TEM/SEM analysis. During sample preparation small sample pieces are embedded in epoxy or acrylic resin, excess resin is trimmed away, and the specimen is sliced into ultrathin sections (50 nm - 100 nm) using a glass or diamond knife.

CRS (Coherent Raman Scattering) microscopy is an umbrella term for label-free methods that image biological structures by exploiting the characteristic, intrinsic vibrational contrast of their molecules. The two most important CRS techniques are Coherent Anti-Stokes Raman Scattering (CARS) and Stimulated Raman Scattering (SRS). The biochemical image contrast of CRS is in many ways complementary to the molecular contrast obtained in fluorescence microscopy. A second crucial advantage of these methods is that they preserve the specimen/sample in a near pristine state. This reference list presents current and basic papers on CRS microscopy.

The need for images in pathology laboratories has significantly increased over the past few years, be it in histopathology, cytology, hematology, clinical microbiology, or other applications. They serve many purposes on top of the documentation of the diagnosis. Yet, the view through the eyepieces and the image are different in nature, the one is an optical image, the other a digital image. Looking at a few aspects of this process that are related cameras will help you make sure you can obtain the images with all the detail and color fidelity you need.

Alzheimer's disease, a genetic and sporadic neurodegenerative condition, leads to cognitive decline in mid to late life, marked by β-amyloid plaques and tau tangles. With limited treatment options, new investigative strategies are crucial. The Cell DIVE multiplexed imaging solution allows examination of Alzheimer's brain tissue, potentially uncovering new research avenues. Here, we showcase the Cell DIVE image viewer, enabling users to access the full Alzheimer's multiplexed dataset directly in their browser.
