摘要: A rapid cell-permeating probe NJUXJ-1 was introduced for sensitive and selective detection of sulfite in living cells. It generated a turn-on response to with high sensitivity (detection limit 13.0 nM) selectivity (at physiological level) low toxicity. The fluorescence the detecting system steady wide pH range (5–8) long period time (over 12 h). most attractive point, its ability, made it suitable bioimaging 2 min incubation shortened whole (cell-permeation reaction), thus could decrease background interference. offered convenient approach determining exogenous or endogenous levels cells further applications.
