Notes: DAR-4M is a rhodamine-based photostable fluorescent probe for the detection of nitric oxide (NO).{35851} The fluorescence intensity of DAR-4M increases with increasing NO concentration, however, the fluorescent yield can be increased further in the presence of both NO and other reactive nitrogen species (RNS), but not in the presence of non-NO RNS alone.{35851,66655} Upon oxidation, DAR-4M is converted to the triazole, DAR-4M T, which displays absorption/emission maxima of 554 and 572 nm, respectively.{35851,66656}
