Magnetic hyperthermia-induced drug release from ureasil-PEO-γ-Fe₂O₃ nanocomposites

Abstract

International audienceA multifunctional material suitable for cancer therapy, which combines stimuli-responsive properties for drug delivery and magnetic hyperthermia prepared by a one-pot sol–gel synthesis from the conjugation of ureasil cross-linked poly(ethylene oxide) (U-PEO) hybrid materials with superparamagnetic nanoparticles (γ-Fe2O3), is reported in this communication

pH-sensitive magnetic alginate/γ-Fe2O3 nanoparticles for adsorption/desorption of a cationic dye from water

“…Magnetic nanoparticles and more particularly iron oxide nanoparticles have been widely studied and used since a long time in many fields such as hyperthermia, magnetic drug delivery, magnetic resonance imaging, data storage, environmental remediation and so on (3)(4)(5)(6)(7)(8)9,10). These applications often need a surface engineering of the magnetic nanoparticles and the research of appropriate compounds to introduce additional functionalities to the nanoparticles attracts more and more attention.…”

Biomedical Response and Different Applications of Magnetic Nanomaterials

“…For such applications size of the nanoparticles should small and within the superparamagnetic behavior range such that they can move more freely in vessels and they are detected by immune system rarely; thus, their retention time in blood is augmented. [34]. Quan et al [35] Used HSA coated iron oxide nanoparticles as drug delivery vehicles for cancer therapy [35].…”
