Photoactivation definition
WebPhotoactivation illuminators can be integrated into microscope systems and are able to focus UV light sufficient for photorelease within a small region of the specimen, even within a single cell. This capability allows the properties of subcellular microenvironments to be examined and also makes it possible to study spatial and temporal aspects ... WebDec 1, 2006 · Fluorescence photoactivation localization microscopy (FPALM) analyzes thousands of single fluorophores per acquisition, localizing small numbers of them at a time, at low excitation intensity. To control the number of visible fluorophores in the field of view and ensure that optically active molecules are separated by much more than the width ...
