【Abstract】 A novel method was proposed to prepare a series of functionalized Ag2S nanoparticles capped with various aminopolycarboxylic acids. Based on the RLS intensities enhanced by BSA-induced Ag2S nanoparticles aggregation, a sensitive RLS method for the detection BSA at nanogram levels was established. A strong dependence of the detection limits is found for the stability constant (lgKMY) of the silver-aminopolycarboxyl complexs.
