Abstract

Apparatus for recording voltage waveforms resulting from flash illumination of bilayer membranes with sorbed dyes or pigments are described. Time constants of light-induced molecular events which displace electric charge in membranes can be taken directly from these waveforms. The waveforms induced across bilayer membranes by a carbocyanine dye and by chlorophyllin illustrate the apparatus performance. The risetime of the chlorophyllin induced photo-voltages are ˜10ns.
