摘要

铁氧体材料在各个领域都有广泛的应用，特别是在生物医学领域。本研究采用聚乙二醇(PEG-4000)和龙骨草(GL)提取物作为覆盖剂和还原剂，通过生物合成方案制备铁酸镁纳米颗粒(MgFNPs)，以提高MgFNPs的性能，用于有效的热疗应用。使用各种表征技术来确定配制样品的性质。扫描电镜观察到微团聚的球形形貌。XRD结果表明，晶粒尺寸在10 ~ 49 nm之间。VSM证实了样品的超顺磁性。观察到加热能力降低到GL和PEG治疗的程度。然而，通过估算其比损失功率(SLP)，对配制样品进行了热疗应用的进一步研究。样品的SLP在130.6 ~ 290.8 W/g之间。用聚乙二醇封顶的材料在热疗应用中具有更好的性能。

Influence of polyethylene glycol and Gongronema latifolium on the structural, optical and magnetic properties of magnesium ferrite nanoparticles for hyperthermia applications

Ferrite materials have found applications in various fields, particularly in biomedical fields. This work involves the preparation of Magnesium ferrite nanoparticles (MgFNPs) by biosynthesis protocol using polyethylene glycol (PEG-4000) and gongronema latifolium (GL) extracts as capping and reducing agents, to heighten the properties of MgFNPs for effective hyperthermia applications. Various characterization techniques were used to determine the properties of the formulated samples. Spherical morphology with low agglomeration was observed by the SEM analysis. The XRD showed a crystallite size between 10 and 49 nm. The VSM confirmed the superparamagnetic nature of the samples. The heating ability was observed to decrease to the therapeutic rage with GL and PEG. However, further investigations for the hyperthermia application were performed on the formulated samples by estimating their Specific loss power (SLP). The samples showed high SLP between 130.6 and 290.8 W/g. The materials capped with PEG has better properties for hyperthermia applications.

期刊介绍： Materials Research Innovations covers all areas of materials research with a particular interest in synthesis, processing, and properties from the nanoscale to the microscale to the bulk. Coverage includes all classes of material – ceramics, metals, and polymers; semiconductors and other functional materials; organic and inorganic materials – alone or in combination as composites. Innovation in composition and processing to impart special properties to bulk materials and coatings, and for innovative applications in technology, represents a strong focus. The journal attempts to balance enduring themes of science and engineering with the innovation provided by such areas of research activity.
