The present invention is cracked uniformly coated on TiO 2 nanoparticles it relates to a process for the preparation of gold / TiO 2 composite nanoparticles that can be used in vitro diagnostic reagents.n n n The gold / TiO 2 composite nanoparticles prepared according to the present invention have a high specific surface area when used as nanoparticles of in vitro diagnostic reagents, so that they can bioconjugate relatively large amounts of biomaterials (DNA, antibodies, etc.) and thus the accuracy of diagnosis results. In addition, the economic effect of reducing the use of expensive gold precursors can be obtained. In addition, in vitro diagnostic reagents using nanoparticles are in the early stages of development but have diverse applications, and are expected to have high growth potential.n n n n Gold, TiO2, composite nanoparticles, in vitro diagnosis |
