Antibacterial mechanism and clinical application of nano titanium dioxide
The risk of patient infection inevitably increases with the use of more invasive operations in the intensive care unit(ICU),including endotracheal tubes,indwelling catheter,central venous catheter,etc.The preparation of antibacterial coatings is an effective way to solve such infections.Antibacterial coatings,such as silver nanoparticles coating,zinc oxide coating,methyl blue coating,antimicrobial peptides coating,and nano titanium dioxide(TiO2)coating,can effectively prevent the formation of biofilms on the surface of implant materials.As a photocatalyst,TiO2 has excellent photocatalytic and antibacterial activity,non-toxic and biocompatible properties,strong physical and chemical stability,and long-lasting antibacterial properties,which makes it high value for research.This review summarizes the bactericidal mechanism and clinical application of TiO2,offering valuable reference for clinical practice.
