The probe could selectively and sensitively respond to H<sub>2</sub>O<sub>2</sub> within 10 min. In addition, this probe was successfully applied for monitoring and imaging of H<sub>2</sub>O<sub>2</sub> in liver cancer HepG2 cells under physiological conditions.RSC advancesA novel ratiometric fluorescent probe for rapid detection of hydrogen peroxide in living cells.PMC90761122019JJ4043481601471B2018004881701754Liu JXu PZhang JChen ZZhang HHu LXiao EfalseA novel ratiometric fluorescent probe for rapid detection of hydrogen peroxide in living cells.In this work, we present a new ratiometric fluorescent probe JNY-1 for rapid and convenient detection of H<sub>2</sub>O<sub>2</sub>.
