We can see objects as small as 0.1 millimeters, and that means we can just about see these lice eggs in our hair and tiny single-celled organisms like amoeba. But it's possible to see things much ...

Biomedical research involves getting a close look at what’s happening inside of cells. Usually, that happens after cells are grown on a glass slide and then fixed in place. They can then be treated so ...

For centuries, biological imaging was myopic; visualization stopped at about 10 μm of tissue depth. Detailed observation of tissue came with a death sentence for the tissue (fixation) so that it could ...

Small modifications to an ordinary optical microscope have helped turn it into a powerful instrument that can be used for studying complex cellular biology in real time at the nanoscale level. And ...

Fundamentally, a microscope comprises two subsystems: an illumination system to illuminate the sample and an imaging system that produces a magnified image of the light that has interacted with the ...
