- Abstract
The article focuses on photoreactivity and cell adhesiveness of amino-group-modified titanium dioxide nanoparticles on silicone substrate, coated by covalent linkage. From the fact that the composite shows good tissue adhesiveness in animal implant tests, it is expected to be able to prevent initial germ infection from the outside when the medical device is percutaneously implanted into a living body. Cationic groups such as amino-groups promote initial cell adhesion and growth. Aminogroups play effective rolls in both cell adhesion and in making covalent bonding with the silicone substrate. This composite also has good cell adhesiveness.
