内容简介：Analytical chemists always develop new techniques like capillary electrophoresis, quantitative cytometry, electrochemical methods with micro and nanoscale probes for analysis in cells. These measurements will help us to change the world we live in. we work on projects that span all of the traditional areas of analytical chemistry including separations, spectroscopy, electrochemistry, mass spectrometry and microscopy. We have specific strengths in 1) imaging including fluorescence (both ratiometric and lifetime based), electrochemistry, and mass spectrometry, 2) biosensing, 3) nanobioengineering, 4) artificial cell structures, and 5) single cell analysis.  The key dynamic event in neuronalcommunication is the release of transmitter molecules through a process called exocytosis. Steady state amperometry is still the most popular electrochemical method for biological assays, because of its excellent, submillisecond,time resolution.This presentation will focus on how to design and apply small electrochemical sensors for studies in the single cell level and thus to obtain rich information of nature in exocytosis.
