Cyclic current-voltage characteristics of a bilayer lipid membrane in the presence of porphyrin (Երկշերտ լիպիդային թաղանթի ցիկլային վոլտ-ամպերային բնութագրիչները պորֆիրինի առկայության դեպքում)

Abstract

The influence of Co-metalloporphyrins on electrical parameters of planar bilayer lipid membranes (BLM) has been investigated. The cyclic currentvoltage characteristics (CVC) of BLM have been measured both in the absence and presence of porphyrin in the solution surrounding the membrane. Based on the measured cyclic current-voltage characteristics the specific conductivity and capacity of BLM were calculated. In the presence of porphyrins the conductivity and capacity of BLM were shown to be increased.
