Common uorescent agents include organic uorophores (e.g., Cy5), uorescent proteins (e.g., GFP), and semiconductor quantum dots each with different size, photobleaching, blinking, and labeling ef ciency properties. Wideeld detection with EMCCD camera enables parallel measurements. The temporal resolution is >ms, and the working concentration is limited to nM or less. Confocal detection from an effective volume of ~10-15 l with an avalanche photodiode or photomultiplier tube. The temporal resolution is
