A highly sensitive and reductant-resistant fluorescent probe for nitroxyl in aqueous solution and serum†
Abstract
A novel coumarin-based fluorescent probe, P-CM, for quantitative detection of nitroxyl (HNO) was developed. P-CM exhibits a selective response to HNO over other biological reductants and was also applied for quantitative detection of HNO in bovine serum with satisfactory results.
