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.

Modification of metal nanoparticles for improved analyte detection by surface enhanced Raman spectroscopy (SERS)

Devices and methods for separating and detecting analytes in a sample. The separation can be accomplished utilizing capillary electrophoresis (CE) or high-performance liquid chromatography (HPLC). The detection can be accomplished by surface enhanced Raman scattering.
