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.
