When fluorophores absorb of a specific wavelength of light (called the excitation wavelength), their electrons move to a higher energy level. These electrons then produce a longer wavelength (called ...

A multidisciplinary team of researchers gives birth to a unique method that enables instant, specific labeling of individual cells, Cell Labelling via Photobleaching (CLaP). This method will become a ...

Conventional light microscopy is limited in its resolving power by the Rayleigh limit to length scales on the order of 200 nm. On the other hand, spectroscopic techniques such as fluorescence ...
