TREATING MATERIAL FOR HARMFUL SUBSTANCE AND METHOD FOR PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a treating material for harmful substances capable of efficiently inactivating these harmful substances by a titanium dioxide film. SOLUTION: The titanium dioxide 5 inactivates harmful substances 2 such as Escherichia coli and HIV which are in danger of being mixed in a material to be treated such as blood plasma with a photocatalyst function. A retaining substance 8 having a specificity retaining only specific harmful substance 2 is crosslinked on the surface of the titanium dioxide 5 in parallel by a monomolecular crosslinking molecule 7. As a result, since the film thickness of the crosslinking molecule 7 becomes thicker, the crosslinking molecule 7 scarcely inhibits inactivation of the harmful substance which the retaining substance 8 retains by photocatalyst function of the titanium dioxide film 5. The treating material can efficiently inactivate the harmful substance 2 which the retaining substance 8 retains by the photocatalyst function of the titanium dioxide film 5.
