Enzyme, Antibody, and Photocatalytically Active Nanoscale Scavengers and Sensors for CW and Biological Agents

Abstract

Thin films consisting of photoactive TiO2 and enzyme-functionalized polymer were studied for their activity against chemical agent simulants. The photochemistry of TiO2 was quantitatively studied for several molecules, including the activation of molecular oxygen which then oxidizes organic molecules. An important discovery is that the rate of the photoprocess is proportional to the square root of the ultraviolet light flux. The enzyme functionalized polymer films were produced to incorporate an indicator indicating that a specific chemical agent was being hydrolyzed. In addition methods to protect the polymer film from photooxidation on contiguous TiO2 surfaces were devised.
