Rapid Colorimetric Detection of Free and Complexed Cr3+ Based on a Tetrabutylphosphonium Bromide/Gold Nanoparticle Anti-Aggregation System

Existing colorimetric sensing strategies based on gold nanoparticles (AuNPs) are largely limited to the detection of free metal ions, leaving metal–organic complexes widely present in real water bodies undetectable. Herein, we develop a simple colorimetric method based on the anti-aggregation effect of bare AuNPs for t...
