For centuries, biological imaging has relied on dyes and fluorescent labels to visualize cellular structures -- a practice that not only alters samples but can delay critical medical decisions.

A team of researchers at the University of California, Los Angeles (UCLA) has introduced a virtual Gram staining technique that could transform how microbiologists stain and classify bacteria. This ...

To ensure that the tissue structures of biological samples are easily recognisable under the electron microscope, they are treated with a staining agent. The standard staining agent for this is ...

To stain cells for examination with a light microscope. To examine a range of cells and other structures with a microscope to understand their basic structure. When viewing any slide with a microscope ...

Researchers at TU Graz have proven that espresso is a favourable alternative to the highly toxic and radioactive uranyl acetate in the analysis of biological samples. To ensure that the tissue ...
