Curcumin-derived carbon quantum dots: Dual actions in mitigating tau hyperphosphorylation and amyloid beta aggregation.

The amyloid cascade and tau hypotheses both hold significant implications for the pathogenesis of Alzheimer's disease (AD). Curcumin shows potential by inhibiting the aggregation of amyloid beta (Aβ) and reducing tau hyperphosphorylation, however, its use is limited due to issues with solubility and bioavailability. Carbon dots, recognized for their high biocompatibility and optimal water solubility, have demonstrated the capability to inhibit either Aβ or tau aggregation.
