Titanium oxide immobilized with bioreceptors and antibacterial method using the same

摘要

Disclosed is an antibacterial composition comprising titanium oxide particles immobilized with an antibody having affinity and cognitive power to a microorganism of interest, and a method for sterilizing the microorganism by using the same. In particular, the present invention relates to a method for preparing functional titanium oxide particles capable of recognizing a microorganism or a virus of interest, and a method for selectively and efficiently sterilizing the same by using the functional titanium oxide particles, and not for randomly sterilizing microorganisms or viruses by using conventional titanium oxide particles having no recognition power to a microorganism or a virus of interest.

主权项

1. A modified titanium oxide particle, comprising a titanium oxide particle and a bioreceptor immobilized thereon by a functional group linked to the titanium oxide particle, in which the bioreceptor has specific binding affinity to a microorganism of interest through a functional group of the bioreceptor.
