Ciliates, a group of single-celled ciliated eukaryotes, have been studied since the dawn of light microscopy, with over 10,000 species described. Cilia are the key feature of ciliates and contribute ...

Living organisms are complex systems with scales of organization spanning the range from Angstroms to meters. Even when consideration is limited to single cells and smaller, there is still a range of ...

A new microscopy method enables researchers to visualize the activity of the enzymes caspase-3 and alkaline phosphatase in various biological samples (Nat. Methods 2024, DOI: ...

Researchers have proven that espresso is a favourable alternative to the highly toxic and radioactive uranyl acetate in the analysis of biological samples. (Nanowerk News) To ensure that the tissue ...

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 ...

Sensing: point-of-care sensors, mobile-phone enabled sensors, field-based sensing and measurement systems with applications in mobile health and telemedicine, environmental monitoring (for example, ...

Minutes matter when a surgeon is deciding how much tissue to remove. Yet for centuries, medical imaging has leaned on stains ...

DAPI, or 4,6-diamidino2-phenylindole, is a fluorescent nucleic acid dye used to preferentially stain double-stranded DNA. There is some evidence that it preferentially binds AT clusters present in the ...

A new X-ray imaging technique could transform how hospitals analyze tissue samples, potentially speeding up diagnoses and ...
