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 ant...
