Magnetic hyperthermia (MHT) is a therapeutic modality for the treatment of solid tumors that has now accumulated more than 30 years experience. In ongoing MHT clinical trials brain and prostate tumors, iron oxide nanoparticles are employed as intra-tumoral agents under patient-safe 100 kHz alternating magnetic field (AMF) applicator. Although currently approved by FDA imaging purposes anemia, (MNPs) designed efficient must respond to specific physical-chemical properties in terms magneto-energy conversion, heat dose production, surface chemistry aggregation state. Accordingly, past few decades, these requirements have boosted development new generation MNPs specifically aimed MHT. this review, we present an overview on their assemblies produced via different synthetic routes, focusing which MNP features allowed unprecedented heating efficiency levels be achieved highlighting nanoplatforms prevent loss intracellular environment. Moreover, review advances MNP-based embrace concept multimodal therapy, aims combine with chemotherapy, radiotherapy, immunotherapy, photodynamic or phototherapy. Next, better control temperature at tumor, focus studies optimized maintain gold-standard performance also tackling aim quantitatively assess amount tumor site regulate conditions. To conclude, future perspectives guidance how advance therapy will provided.

Abstract Magnetic nanoparticles (MNPs) offer tremendous potentialities in biomedical applications for a long while. Since these materials' interactions biological media largely rely on their crystal structures, sizes, and shapes, detailed studies synthesis mechanism medicinal aspects are crucial. Despite many review reports that have already been published MNPs, they mainly focused either perspective or characterization along with functionalization mechanisms as individual entities. For this reason, uncovers comprehensive insight into the ongoing improvement of fabrication processes, surface MNPs together. Besides, various magnetic nanocomposite (MNCs) smart drug delivery, recent hyperthermia treatment, lab‐on‐a‐chip, bio‐separation, some emerging imaging techniques using discussed. A analysis toxicity, challenges, progress clinical trials is sketched out to open numerous entryways advanced research applications.

Superparamagnetic iron oxide nanoparticles (SPIONs) have attracted attention in the biomedical field thanks to their ability prompt hyperthermia response an alternated magnetic field. Hyperthermia is well known for inducing cell death, particular tumour cells, which seem a higher sensitivity temperature increases. For this reason, has been recommended as therapeutic tool against cancer. Despite potentialities of approach, little still about effects provoked by at molecular level, and death mechanisms that are activated. Nevertheless, in-depth knowledge aspect would allow improvement outcomes favour clinical translation. Moreover, last few decades, lot effort put into finding effective delivery strategy could improve SPION biodistribution localisation action site. The aim review provide general outline hyperthermia, focusing on interactions with fields, new strategies efficiently deliver them target site, recent vitro vivo studies proposing possible pathways activated treatment.

The photothermal use of iron oxide magnetic nanoparticles (NPs) is becoming more and popular documented. Herein, we compared the (PT) therapy potential versus hyperthermia (MHT) modality nanospheres, largely used in biomedical field multicore nanoflowers known among best nanoheaters. NPs were imaged using transmission electron microscopy their optical properties characterized by UV-Vis-NIR-I-II before oxidation (magnetite) after to maghemite. efficiency all MHT PT preferred second near-infrared (NIR-II) biological window was carried out water cancer cells. We show that, water, magnetite are most efficient nanoheaters for both modalities. Moreover, appears much than at low NP dose, whatever NP. In cellular environment, PT, totally conserved, with as performers MHT, which lost. Finally, cell uptake significantly increased nanospheres. antitumor investigated same dose delivered cells reasonable laser power density (0.3 W/cm2), showed almost total death nanoflowers.
