Abstract Cuprum-enriched cuprum sulfide nanoparticles (CuS/Cu2+) were prepared.The nanoparticles are water-soluble.They could be used as a resonance light scattering(RLS) probe in the determination of human gamma globulin, which was proved to be a simple, rapid and specific method.In comparison with organic dye probes, these nanoparticles probes are brighter, more stable against photobleaching, and do not suffer from blinking.Under optimum conditions, the response is linearly proportional to the concentration of gamma globulin between 0.1 and 1.5 mg·L-1, and the detection limit is 0.064 6 mg·L-1.
