The scientific community has made great efforts in advancing magnetic hyperthermia for the last two decades after going through a sizeable research lapse from its establishment. All progress various topics ranging nanoparticle synthesis to biocompatibilization and vivo testing have been seeking push forefront towards some new clinical trials. As many, they did not go at expected pace. Today, fr...

In the past decades, there is a growing interest in the design and synthesis of composite microspheres with a dielectric solid sphere (e.g., silica, polystyrene) covered by metallic and their corresponding metal oxides shell, such as copper[1], gold[2], silver[3,4], iron oxide[5], zinc oxide[6,7], titanium oxide[8,9] and zirconium dioxide[10]. Such materials may exhibit a few unique electrical,...

Magnetic nanoparticle based hyperthermia emerged as a potential tool for treating malignant tumours. The efficiency of the method relies heavily on knowledge magnetic properties samples; in particular, frequency dependent complex susceptibility is vital to optimize irradiation conditions and provide feedback material science developments. We study frequency-dependent an aqueous ferrite suspensi...

Abstract The main aim of the present work is to determine temperature distribution in normal and cancerous tissues achieve desired condition hyperthermia. Hyperthermia can be defined as mild elevation 40–46 °C, which induces cancer cell death enhances effects radiotherapy chemotherapy. In research, realistic geometry human head layers tumor are modelled, geometrically, then simulated similar re...

This review describes recent advances in the handling and manipulation of magnetic particles in microfluidic systems. Starting from the properties of magnetic nanoparticles and microparticles, their use in magnetic separation, immuno-assays, magnetic resonance imaging, drug delivery, and hyperthermia is discussed. We then focus on new developments in magnetic manipulation, separation, transport...

The synthesis, characterization and property evaluation of drug-loaded polymer-coated magnetic nanoparticles (MNPs) relevant to multimodal cancer therapy has been studied. The hyperthermia and controlled drug release characteristics of these particles was examined. Magnetite (Fe(3)O(4))-poly-n-(isopropylacrylamide) (PNIPAM) composite MNPs were synthesized in a core-shell morphology by dispersio...
