As a natural antitumor drug, curcumin (CUR) has received increasing attention from researchers and patients due to its various medicinal properties. However, currently CUR is still restricted due to its low and stand-alone therapeutic effects that seriously limit its clinical application. Here, by using cellulose nanocrystals (CNCs) as a nanocarrier to load CUR and AuNPs simultaneously, we developed a hybrid nanoparticle as a codrug delivery system to enhance the low and stand-alone therapeutic effects of CUR. Aided with the encapsulation of β-cyclodextrin (βCD), both the solubility and the stability of CUR are greatly enhanced (solubility increased from 0.89 to 131.7 μg/mL). Owing to the unique rod-like morphology of CNCs, the system exhibits an outstanding loading capacity of 31.4 μg/mg. Under the heat effects of coloaded AuNPs, the system demonstrates a high release rate of 77.63%. Finally, with CNC as a bridge nanocarrier, all aforementioned functions were integrated into one hybrid nanoparticle. The all-in-one integration ensures CUR to have enhanced therapeutic effects and enables the delivery system to exhibit combined chemo-photothermal therapy outcomes. This work presents a significant step toward CUR's clinical application and provides a new strategy for effective and integrative treatment of tumor disease.
