One-pot synthesized Cu/Au/Pt trimetallic nanoparticles with enhanced catalytic and plasmonic properties as a universal platform for biosensing and cancer theranostics

Abstract

Cu/Au/Pt trimetallic nanoparticles (TMNPs) with enhanced catalytic activity and intense plasmonic absorption in the NIR-I biowindow (650-950 nm) were prepared using a fast, gentle and one-pot protocol. Based on these properties and assembly of thiolated-aptamers on Cu/Au/Pt TMNPs, a universal platform was developed for applications in biosensing and theranostics.
