    • PURPOSE: A surface silica coating method of gold nano-rods capable of selectively controlling the coating thickness of silica layers a nano-hybrid manufactured by the method are provided to stably coat the gold nano-rod surface with silicate without a surface mediator. CONSTITUTION: A surface silica coating method of gold nano-rods comprises the following steps: preparing gold nano-rods; and mixing and agitating the gold nano-rods with a mixture of a polymer having amine group and a polymer having mercapto group in order to coat the gold nano-rod surface with silicate layer. The polymer having amine group is APDES(3-aminopropyldimethyl-ethoxysilane) and the polymer having mercapto group is MPTMS(3-mercaptopropyl-trimethoxysilane). A nano-hybrid manufacturing method comprises the following steps: preparing the gold nano-rods and silica nano-balls; forming amine group on the surfaces of each silica nano-ball and gold nano-rod; and combining the silica nano-ball on the surface of the gold nano-rod by reacting the gold nano-rod and the silica nano-ball with NHS-PES-NHS.
