## Abstract We have characterized a commercial confocal scanning head for the detection of single molecule fluorescence by twoβphoton excitation. We have verified that the distribution of the fluorescence emitted by dyes and labeled proteins on glass substrates is discrete with quanta proportional
## Abstract __We report the twoβphoton excitation and emission of a recently developed green fluorescent protein (GFP) mutant, E__^__2__^__GFP. Two main excitation bands are found at 780 and 870 nm. Blinking and irreversible and reversible bleaching were observed. Fluorescence blinking occurs in th
