A ternary system (GOB-SDS) was established for the ratiometric fluorescent detection of Berberine in an aqueous solution. In this (GOB-SDS), fluorescence reporter B grafted onto edges graphene oxide (GO) through amido bond (C(═O)NH). absence sodium dodecyl sulfate (SDS), could be quenched via resonance energy transfer (FRET) due to strong π–π stacking interaction between and GO. With addition SDS, formation a B-SDS micelle weakened GO B, leading recovery B's fluorescence. Then, added. The easy Berberine-SDS instead electrostatic emission at 393 nm again by Meanwhile, AIE behavior (fluorescence 536 nm) enhanced. Thus, sensor (F536 nm/F393 achieved realize sensitive Berberine. characteristics obtained GOB-SDS mechanism were fully studied using various methods. addition, high stability, selectivity, sensitivity, anti-interference, sustainability toward also demonstrated; showed good linear range from 0 8.90 μM (0 3.00 μg/mL) with limit 23.4 nM (8.17 ng/mL). Furthermore, used detect real drugs low background, combination smartphone applied on-site analysis
