Abstract:
Titanium dioxide nanoparticles and a method for immobilizing a bio-material to the titanium dioxide are provided to enlarge an optical thickness change value generated in an antibody-antigen reaction by a resonance reflection light biosensor. Titanium dioxide nanoparticles comprise: titanium dioxide whose surface has hydroxyl groups; an aldehyde group layer introduced on the hydroxyl groups of the titanium dioxide by self-assembly; and a bio-material immobilized on the aldehyde group layer. The titanium dioxide reacts to the piranha solution to form the hydroxyl groups. The aldehyde group layer is formed by a reaction between the titanium dioxide and an aldehyde silane solution.
