    Abstract: In accordance with an aspect of the present invention, there is provided an Au/Ag core-shell composite including an Au nanoparticle; an Ag nanoparticle layer surrounding the Au nanoparticle; and a receptor having a target material recognition site bondable or reactable with a target material, wherein one end of the receptor is bonded on the surface of the Au nanoparticle, so that a portion of the receptor is embedded into the Ag nanoparticle layer, and the target material recognition site is exposed to the outside of the Ag nanoparticle layer. The Au/Ag core-shell composite can provide a stable bond between Au nanoparticle and organic molecule, and superior optical characteristics of Ag nanoparticle. Thus, a biosensor using the composite in accordance with an aspect of the present invention can effectively and efficiently detect target bio material and be variously used in medical and pharmaceutics.
