METAL NANOWIRE FORMED WITH GOLD NANOCLUSTER ON THE SURFACE FOR BINDING A TARGET MATERIAL AND METHOD FOR BINDING THE METAL NANOWIRE WITH THE TARGET MATERIAL

摘要

PURPOSE: A metal nanowire in which gold nanocluster is formed on the surface and a method of binding for the metal nanowire with target material are provided to efficiently bond with target material at high affinity. CONSTITUTION: A metal nanowire in which gold nanocluster is formed on the surface is existed in the composition form. The gold nanocluster has average size of 1-10 nano meters. The gold nanocluster is existed in the density range of 1X10^6 - 1X10^16clusters/cm^2. A manufacturing method of the metal nanowire comprises the following steps: forming a gold thin film layer on a metal board; forming gold - metal island by primary sintering the gold containing metal substrate in a chamber for chemical vapor deposition; and injecting mixing gas into the chamber while secondary sintering the silicon substrate to grow metal nanowire in which gold nanocluster is formed on the surface.
