Self-assembled sustainable bionanocomposite hydrogels from chitosan for the combination chemotherapy of hydrophobic and hydrophilic drugs.

Self-assembled hydrogels derived from naturally sourced polymers have gained significant interest in drug delivery applications, owing to their potential, exceptional biocompatibility and sustainable properties. This work presents the development and application of self-assembled nanocomposite hydrogels from chitosan and nanosilver as a pH responsive drug delivery system for the controlled release of doxorubicin and paclitaxel in anticancer therapy. Chitosan was functionalized with 4-formyl benzoic acid for incorporating both hydrophobic and hydrophilic anticancer drugs.
