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

Chem Commun (Camb). 2008 Feb 21:(7):880-2. doi: 10.1039/b716270g. Epub 2007 Dec 18.

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 x 10(-6) M, providing a new tool for the direct measurement of histidine.
