摘要
The present invention relates to the microsphere whose surface is covered with hot spots and the method for identifying chemicals through Surface Enhanced Raman Scattering (SERS) using the same. The microsphere having hot spots, according to the present invention, includes a microsphere and metal networks as a shell which covers the surface of the microsphere, and nano-sized pores are distributed randomly on the surface or in the interstitial space of the metal networks. The microsphere having hot spots, according to the present invention, can be individually manipulated under a conventional optical microscope. SERS spectra of the monolayer of molecules on Pt or Au can be measured using single microsphere having hot spots mentioned as a sensitive probe. The microsphere having hot spots can be applied for decoding the microspheres with Raman tags flowing in a microfluidic system.
