A new fluorescent sensor combining phenothiazine and indolium, which reacts specifically with the cyanide ion with a large Stokes shift and a good fluorescence quantum yield, was prepared. When CN-.
A novel fluorescence immunoassay protocol, using high quantum yield of carbon dots as fluorescent labels, was developed for rapid quantitative determination of the model analyte human immunoglobulin G.
Easily synthesized high quantum yield sulfur- and nitrogen-doped carbon dots can serve as a very efficient fluorescent sensor for the detection of Cr(vi).
Novel turn-on fluorescent sensor for cyanide ion based on the charge transfer transition of phenothiazine/indolium compounds
