摘要
Peroxynitrite (ONOO-), a highly reactive species, plays a key role in various physiological and pathological processes. Herein, a red-emitting fluorescent reporter perylenemonoimide-boronate ester (PMI-BE) was synthesized and utilized for ultrasensitive detection of ONOO-. The unique feature of PMI-BE is its nanomolar sensitivity with high selectivity towards ONOO-. Moreover, PMI-BE also detects endogenously generated ONOO- in live cells. Red-emitting PMI-BE was synthesized for ultrasensitive nanomolar detection of peroxynitrite. PMI-BE also responds to endogenously generated peroxynitrite in live macrophase cells.
