Ultramicrotomy is a specialized sectioning technique used to prepare ultra-thin slices of biological specimens for examination under an electron microscope. This process involves cutting samples into slices that are typically 50-100 nanometers thick, allowing researchers to visualize cellular structures at the nanoscale level. Ultramicrotomy is critical for studying the ultrastructure of cells and tissues, as it enables high-resolution imaging and analysis of fine details that would otherwise be obscured in thicker samples.
congrats on reading the definition of Ultramicrotomy. now let's actually learn it.
