Researchers from Tokyo Metropolitan University have found that the motion of unlabeled cells can be used to tell whether they ...

Now phase-contrast microscopy, interference microscopy, Schlieren and dark-ground illumination are essentially methods for revealing small variations in refractive index (or strictly, optical path).

The team of researchers, led by Professor Hiromi Miyoshi, came up with a way of tracking cells using phase-contrast microscopy, one of the most common ways of observing cells. Phase-contrast ...
