Pathologists often use tissue samples and microscopy to help diagnose diseases like cancer. But distinguishing different cells often require several stages of staining. Now researchers are presenting ...

For centuries, scientists have used microscopes to magnify and peer into a world invisible to the naked eye. The earliest instruments were simple lens-filled tubes, the best of which revealed the ...

When we look at biological cells under a microscope, they’re usually not very colourful. Normally, to visualise them we have to artificially add colour — typically by staining. By doing so, we can see ...

Breast cancer is one the leading causes of cancer death among women globally. Upon breast cancer diagnosis, the testing of HER2—a protein that promotes cancer cell growth, is routinely carried out to ...

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 ...
