電荷（電子與離子）在軟界面上的轉(zhuǎn)移反應(yīng)在理解化學(xué)傳感器機(jī)理、相轉(zhuǎn)移催化、藥物釋放與模擬生物膜等方面發(fā)揮著重要作用[1]。
在該報(bào)告中，我們將介紹近期我們課題組在軟界面電分析化學(xué)研究中的進(jìn)展，主要包括電荷轉(zhuǎn)移反應(yīng)動(dòng)力學(xué)、采用掃描離子電導(dǎo)顯微鏡（SICM）探討液/液界面的結(jié)構(gòu)、微、納米管所產(chǎn)生的離子整流現(xiàn)象等[2-4]。

Charge (electron and ion) transfer reactions at a soft interface are fundamental significant in the understanding of the mechanism of chemical nsors, pha transfer catalysis, drug delivery and mimicking biological membranes.1
In this prentation, we will discuss some recent progress on investigations of charge transfer process at the soft interfaces in our laboratory. It focus mainly on the transfer kinetics, the structure of liquid/liquid interface by scanning ion conductance microscopy (SICM) and rectification. Very fast ion transfer rate constants can be obtained bad on nanopipet voltammetry.2-4
