Carbazole-based near-infrared-emitting fluorescence probe for the detection of bisulfite in live animals and real food samples

Abstract

Bisulfite (HSO3–) as a significant food additive is diffusely used in pharmaceutical products and various foodstuffs due to its antibacterial, antioxidant and bleaching properties. Meanwhile, as a derivative of biological...

A fluorescence “turn-on” probe for the detection of HSO3− based on a pyrene-functionalized mesoporous silica material

“…2,12 − 16 However, these organic-based probes, such as iridium complex, 17,18 rhodamine 19 and coumarin, 20 and the probes based on the cooperative function of serum albumins (such as BSA and HSA) and HSO 3 − 21 − 24 are greatly limited by the complexity of their synthesis, poor selectivity for HSO 3 − , poor water solubility and the need for organic solvents. 19,25 In order to combine the advantages of inorganic and organic functional groups, organic–inorganic hybrid-based nanomaterials, such as quantum dots and metal–organic frameworks, have been designed as fluorescent probes for the detection of HSO 3 − . 26–28 However, these nanomaterial-based fluorescent probes required cumbersome preparation procedures and lack dispersion stability in aqueous solution.…”
