This study introduces a novel green hydrothermal synthesis approach using lotus seed plumules to prepare carbon quantum dots (L-CQDs) and systematically evaluates their potential applications in folic acid (FA) detection and bioimaging. L-CQDs, enriched with phytochemical constituents such as alkaloids and flavonoids, exhibit superior optical properties, biocompatibility, and low toxicity. For FA detection, L-CQDs demonstrated high sensitivity and specificity, achieving a limit of detection (LOD) of 0.

Hypochlorite and ascorbic acid (AA), play an indispensable role in numerous physiological activities. Herein, a ratiometric colorimetric sensing strategy for the determination of hypochlorite and AA was developed via the catalytic oxidation and reduction of 3,3',5,5'-tetramethylbenzidine (TMB). Interestingly, in the presence of FeO-MOF-5(Fe) and hypochlorite, TMB complexes in acidic environments were oxidized to blue oxidized TMB and further diazotized to produce yellow-green diazotized TMB, resulting in the hypochlorite concentration-dependent ratiometric variation for the absorbance at 652 and 450 nm (A/A).
