Quinoid to benzenoid transition-driven glutathione sensing: Dual-emission carbon dots and smartphone-based ratiometric fluorescence analysis

Quinoid to benzenoid transition-driven glutathione sensing: Dual-emission carbon dots and smartphone-based ratiometric fluorescence analysis

This study presents a novel and sensitive method for the determination of glutathione (GSH), a crucial antioxidant and cellular protectant, using dual blue/orange-emitting carbon dots (BOCDs) and phenolphthalein (PHP). The sensing system operates at pH 9.0, exploiting the unique optical properties...
