Synthesis of Mesoporous Core Shell Magnetite Bioactive Glass Nanoparticles for Magnetic Hyperthermia Treatment of Cancer

Abstract

AbstractMultiple biological advances have made use of bioactive glass (BG) nanoparticles (NPs) in regenerative medicine, bone and tooth repair, drug and gene transfer, cancer treatment, and cosmetics. Normal biocompatible coatings alongside hydrocarbons, polymers, and silica significantly affect fundamental attributes of NPs. In this study, we synthesized a novel mesoporous BG NPs with magnetite core shell (AMAG_BG) using L‐arginine as a template processing magnetic hyperthermia (MH). BG network coverage on magnetite (AMAG) NPs were orchestrated first time by bio‐inspired synthesis in watery dissolvable. AMAG and AMAG_BG NPs were characterized by utilizing FE‐SEM, HR‐TEM, and BET analysis. The elemental composition of L‐arginine templated magnetite (AMAG) and AMAG_BG NPs was also determined by XPS and EDX analysis. Characteristics of AMAG_BG were contrasted with bare AMAG NPs in morphology, particle size, porosity, and composition. The fabricated BG NPs′ in‐vitro bioactivity and heat studies were successfully monitored after interaction with simulated bodily fluid (SBF). Magnetic studies and in‐vitro heat studies together demonstrated the behavior of BG NPs towards MH treatment of cancerous cells. Cytotoxicity tests on AMAG_BG NPs using U2OS and human blood cells with appropriate control experiments revealed biocompatibility. The study represents magnetic and thermal property‐dependent sustainable synthetic process of AMAG BG NPs for cancer treatment.
