“…Fluorescent imaging has become an attractive method for detecting various biomolecules due to its advantages of non-invasiveness, high sensitivity, real-time monitoring ability as well as high spatiotemporal resolution [ [15] , [16] , [17] , [18] , [19] , [20] , [21] ]. Due to the prominent properties of fluorescence-based methods, increasing varieties of fluorescent probes have been developed for detecting and imaging H 2 O 2 [ [22] , [23] , [24] , [25] , [26] , [27] , [28] , [29] , [30] , [31] , [32] , [33] , [34] ].…”
