Imaging of cellular activity of single cultured cells by scanning electrochemical microscopy

摘要

Scanning electrochemical microscopy (SECM) based on oxygen reduction current was used for imaging of respiration activity of living animal cells (SW-480). The addition of KCN into the culture medium paled the image of the cells. The semiquantitative analysis of the SECM responses suggested that the membrane permeability of SW-480 cells to CN- is on the order of 10(-7) cm/s. [References: 9]
