Biocompatible and Biodegradable Nanocarriers for Targeted Drug Delivery in Precision Medicine.

ABSTRACT: Despite the promising natural origin, biocompatibility, and biodegradability of chitosan for biomedical applications, developing biodegradable nanocarriers with controllable sizes and precise drug delivery targeting remains a significant challenge, hindering its integration into precision medicine. To address this, we synthesized gold nanocage (AuNCs)/poly-(N-isopropylacrylamide-co-carboxymethyl chitosan) core-shell multifunctional composite nanospheres (CPAu) through a two-step one-pot method. The resulting CPAu nanospheres (~146 nm in size) exhibited multi-sensitive release properties, excellent biocompatibility, and potent photothermal therapy (PTT) activity. These nanospheres effectively encapsulated diverse antitumor drugs while demonstrating triple responsiveness (thermo-, reduction-
