Carrier-mediated photodiffusion membranes

J S Schultz. Science. .

Abstract

Reversible photochromic reactions can be coupled to carrier-mediated transport processes in membranes to bring about the separation or concentration of selected permeants. Carbon monoxide has been pumped against of fourfold concentration gradient by differentially illuminating a hemoglobin membrane. The extent of concentration of photochromic ligands increases with light intensity and is reversible. Nonphotochemically sensitive ligands can also be transported by coupling with phostosensitive carrier-mediated systems.
