“…Due to their wide range of applications in hyperthermia, drug delivery, and magnetic resonance imaging (MRI), various synthesis routes were applied to prepare inorganic magnetic nanocomposites [4][5][6]. Surface modification of magnetic nanoparticles is required to improve their chemical stability [7]. Silica is a suitable material for this modification due to its high mechanical strength and functionalization via silylation [8].…”

In the current study, a facile and in situ synthesis route for the preparation of mesoporous SiO 2 -Fe 3 O 4 magnetic nanocomposite using iron (III) acetylacetonate via microwave-assisted solvothermal method is proposed. To characterize the samples, XRD, EDS, SEM, TEM, BET, and VSM were applied, and their potential applications as drug carriers, hyperthermia, and MRI contrast agents were investigated. The results confirmed that the magnetic nanocomposite could be used as a drug carrier, and its drug release rate is affected by the magnetic field. Also, the product applications as both hyperthermia and MRI contrast agent for T 2 weighted images were approved.
