An off-the-shelf sensor for colourimetric detection of sulfide. Issue 51 (21st December 2016) - Perry, Alexis
Graphical abstract: Highlights: NitroBIPS is a cheap, accessible colourimetric sensor for H2 S. NitroBIPS is highly selective for H2 S against cysteine and glutathione. NitroBIPS can detect nanomolar H2 S concentrations. NitroBIPS functions as an H2 S probe in aqueous media. Abstract: The cheap, accessible spiropyran nitroBIPS is a sensitive, selective colourimetric sensor for quantitative determination of sulfide in aqueous media at neutral pH.
