We introduce a novel sensing mechanism for nitric oxide (NO) detection with a particular easily synthesized embodiment (NO550), which displays a rapid and linear response to NO with a red-shifted 1500-fold turn-on signal from a dark background. Excellent selectivity was observed against other reactive oxygen/nitrogen species, pH, and various substances that interfere with existing probes. NO550 crosses cell membranes but not nuclear membranes and is suitable for both intra- and extracellular NO quantifications. Good cytocompatibility was found during in vitro studies with two different cell lines. The high specificity, dark background, facile synthesis, and low pH dependence make NO550 a superior probe for NO detection when used as an imaging agent.
