Analysis of Electrical Phenomena in Membranes and Interfaces by Absorption Changes

Nature volume 222, page 1062 (14 June 1969) | Download Citation



IN several biological systems electrical phenomena across membranes of 100 Å thickness are important. As yet there has been no straightforward way of measuring electrical phenomena in such membranes. If these membranes are activated, a potential difference of about 100 mV is usually built up across them, corresponding to a field strength of about 105 V/cm.
