Loading polyaniline (PANI) nanoparticles to mesoporous hydroxyapatite (HAp) spheres for near infrared (NIR) induced doxorubicin (DOX) drug delivery and colon cancer treatment

Abstract

In response to the pressing need for more efficient and targeted cancer therapies, this study presents the development of biodegradable hydroxyapatite/polyaniline (HAp/PANI) nanocomposite drug carriers for near-infrared (NIR)-induced drug delivery. The synthesis involved loading polyaniline onto mesoporous hydroxyapatite spheres, resulting in high drug loading capacity and tunable NIR responsiveness. The HAp/PANI spheres exhibited superior photothermal properties compared to pristine HAp under NIR irradiation, along with excellent biocompatibility. Importantly, the drug release behavior could be precisely controlled by adjusting NIR power and irradiation time, leading to enhanced anticancer efficacy against HCT-116 colorectal cancer cells. These findings highlight the potential of HAp/PANI mesoporous spheres as promising drug carriers for NIR-responsive cancer therapy.
