ABSTRACT:
A SERS active particle having a metal-containing particle and a cationic coating on the metal-containing particle, wherein the SERS active particle carries a positive charge is disclosed. Also, a SERS active particle having a metal-containing particle and a non-metallic molecule, wherein the metal-containing particle is derivatized with the non-metallic molecule is disclosed. In addition, several methods of modifying the nanoparticles surfaces of a SERS active particle and of improving the interaction between the SERS active particle and an analyte are disclosed.
