    • 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.
    • 根据本发明的一个方面,提供一种包含Au纳米颗粒的Au / Ag核 - 壳复合材料; 围绕Au纳米颗粒的Ag纳米颗粒层; 以及具有可与靶材料结合或可与靶材料反应的靶材料识别位点的受体,其中所述受体的一端键合在所述Au纳米颗粒的表面上,使得所述受体的一部分嵌入到所述Ag纳米颗粒层中,并且 靶材料识别位点暴露于Ag纳米颗粒层的外部。 Au / Ag核 - 壳复合材料可以在Au纳米颗粒和有机分子之间提供稳定的键合,并且具有优异的Ag纳米颗粒的光学特性。 因此,使用根据本发明的一个方面的复合材料的生物传感器可以有效和高效地检测目标生物材料,并且可以在医疗和药物学中被多种用途。
