Synthesis of para-sulfonatocalix[4]arene-modified silver nanoparticles as colorimetric histidine probes

Author affiliations

Abstract

This Communication reports a novel colorimetric sensor to probe histidine in water based on para-sulfonatocalix[4]arene-modified silver nanoparticles; this highly selective sensor allows a rapid quantitative assay of histidine down to a concentration of 5 × 10−6 M, providing a new tool for the direct measurement of histidine.
