Fecha de publicación: | 15-oct-2021 | Editor: | Elsevier | Citación: | Carbohydrate Polymers 270: 118366 (2021) | Resumen: | Cellulose nanocrystals (CNCs) have advantages as drug delivery carriers because of their biocompatibility and the presence of hydroxyl groups which favor chemical modification and drug binding. The present study describes the development of novel multifunctional rod-like CNCs-based carriers as therapeutic platforms: CNCs were hybridized with folic acid for actively targeting tumor cells, carbon dots (Cdots) for both imaging and photodynamic/photothermal treatments and doxorubicin (DOX) as an anticancer drug. Hybridized carriers displayed excellent drug-loading capacity. Moreover, Cdots-containing hybrids showed fluorescence and photosensitized singlet oxygen generation and photothermal behavior. Carriers exhibited pH-sensitive drug release because of changing interactions with DOX, and this release proved to be effective against in vitro cervical cancer cells, as evidenced by dose-dependent reduced cellular viabilities. Additionally, DOX release was promoted by light irradiation and the photodynamic behavior by reactive oxygen species was confirmed. These results demonstrate the potential of multifunctional CNCs-based carriers as platforms for multimodal photodynamic/photothermal-chemotherapy. | Versión del editor: | https://doi.org/10.1016/j.carbpol.2021.118366 | URI: | http://hdl.handle.net/10261/245190 | DOI: | 10.1016/j.carbpol.2021.118366 |
