HKPerox-2 is an excellently selective and sensitive green fluorescent probe toward H 2 O 2 over 30-fold other tested ROS RNS in chemical and biological systems. HKPerox-2 is a O-methyl rhodol derivative and specifically recognize H 2 O 2 based on a tandem payne dakin reaction.
HKPerox-1 is a yellow-emitting fluorescent probe with excellent selectivity and sensitivity toward H 2 O 2 . HKPerox-1 can be used for molecular imaging of endogenous H 2 O 2 in living cells.
