Abstract |
Nowadays locoregional therapy for cancer treatment can be associated with nanocomposite drug delivery systems. Coated nanoparticles have versatile applications for delivering chemotherapeutic drugs to the targeted part of the body. In this study, a ceramic carrier like nanosized hydroxyapatite (HAp) was synthesized by the in situ precipitation method followed by coating with anticancer drug like doxorubicin (DOX) and polyvinyl alcohol (PVA) polymer. The physicochemical characterization of the prepared polymer-coated drug ceramic nanocomposite (DOX-HAp-PVA) was carried out using Fourier transform infrared spectroscopy, X-ray diffraction, transmission electron spectroscopy, and particle size distribution. Furthermore, the biocompatibility and the anticancer activity of the nanocomposite were explored by MTT assay study. Successfully synthesized DOX-HAp-PVA nanocomposite exhibited a remarkable cytotoxicity toward osteosarcoma cells (MG 63), which may be potentially used as an anticancer agent against osteosarcoma.
