“…Comparing to conventional detection approach, including colormetric assays (Luo et al, 2001 ), GC analyses (Bagheri et al, 2009 ; Chen et al, 2009 ), HPLC (Nash, 1953 ; Soman et al, 2008 ), fluorescence probes are considered as one of the most powerful tools due to their simplified operation, high selectivity and sensitivity, real-time detectability, and biocompatibility (Tang et al, 2015 ; Zhou et al, 2015 ; Bruemmer et al, 2017a ; Xu et al, 2017 ). To date, a number of fluorescent probes for FA visualization have been reported based on the fluorophores of silicon rhodol, 1,8-naphthalimide, resorufin and so forth (Brewer and Chang, 2015 ; Roth et al, 2015 ; He et al, 2016 ; Bruemmer et al, 2017b ; Liu et al, 2017 ; Xie et al, 2017a , b ; Bi et al, 2018 ; Zhou et al, 2018 ).…”
