DETECTION OF GOLD NANOPARTICLES

摘要

A method for detecting gold nanoparticles present in an aqueous sample containing gold nanoparticles, the method including: a. mixing a fluorophore with the aqueous sample containing gold nanoparticles to form a fluorescent gold solution, the fluorophore being a boron-dipyrromethane (BODIPY) dye, the fluorescent gold solution having a BODIPY concentration in a range of from 1.0 nM to 500.0 nM; and b. exciting the fluorescent gold solution in an optical chamber with incident light to produce emitted fluorescent light, collecting the emitted fluorescent light, and determining the concentration of gold nanoparticles in the fluorescent gold solution and thus in the aqueous sample.
