Comb of a lifetime: a new method for fluorescence microscopy
January 1, 2021By
Conventional fluorescence microscopy provides poor quantitative information of the sample because it only captures fluorescence intensity, which changes frequently and depends on external factors.

Their method does not require mechanical scanning of a focal point; instead, it produces images from all points in the sample simultaneously, enabling a more quantitative study of dynamic biological and chemical processes.
