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