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

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 ...

This seminar provides an overview of fluorescence microscopy in cancer research and other cell-based applications in the biosciences discovery workflow. In comparison with phase contrast and ...

When single-molecule super-resolution microscopes were first commercialized some 15 years ago, they made headlines for their ability to resolve individual molecules and structures at the nanometer ...

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.
