Synthesis of amphiphilic graphitic silver nanoparticles with inherent internal standards: an efficient strategy for reliable quantitative SERS analysis in common fluids.

An efficient strategy for reliable quantitative SERS analysis in common fluids was proposed by amphiphilic functionalization of graphitic silver nanoparticles with inherent internal standards by azides, and has the merits of high accuracy, enhanced dispersity and outstanding stability in fluids.
