The functionalized nanoparticles were water soluble and biocompatible and used as fluorescence probe in the determination of Human serum albumin(HSA) and γ globulin( γ G). Under the optimal conditions, linear relationships were found between the enhanced intensity of fluorescence and the concentration of protein in the range of 0 2 and 3 5 μg/mL for HSA and 0 2 and 11 0 μg/mL for γ G. The limits of detection were 0 09 μg/mL for HSA and 0 18 μg/mL for γ G.展开更多
