The secretion from cells plays a significant role in life activities and in
the fields of neurobiology, cell biology, clinic, pathology, pharmacology
etc. Thus to investigate the secretion at the single cell level with the de
veloping methods is a frontier cross-discipline research activity. The cont
ents, methods and new progress of this research have been reviewed by elect
rochemical monitoring combined with patch-clamp techniques, fluorescent det
ection and immunoassay, and the prospects on the frontier of the research a
rea have been discussed.
