论文摘要
磁性纳米颗粒(MNP)已被广泛用作磁性高温治疗中的微小加热来源,磁共振成像中的对比剂(MRI),磁性颗粒成像中的示踪剂(MPI),药物/基因递送的载体等。纳米材料,Miltenyi Biotec,Micromod Partikeltechnologie GmbH和纳米复杂性等。在本文中,我们报告了来自Ocean Nanotech的氧化铁纳米颗粒产品的物理和磁性表征。标准表征工具,例如振动样本磁力计(VSM),X射线衍射(XRD),动态光散射(DLS),透射电子显微镜(TEM)和Zeta电位分析仪,用于为这些铁氧化物纳米药物的概述提供磁性纳米粒子客户和研究人员。此外,在低频和高频交替磁场下研究了这些氧化铁纳米颗粒在水溶液中的动态磁反应,从而为表征来自海洋纳米技术的MNP提供了标准化的操作程序,从而为不同应用提供了最佳的磁性纳米颗粒。
Magnetic nanoparticles (MNPs) have been extensively used as tiny heating sources in magnetic hyperthermia therapy, contrast agents in magnetic resonance imaging (MRI), tracers in magnetic particle imaging (MPI), carriers for drug/gene delivery, etc. There have emerged many magnetic nanoparticle/microbeads suppliers since the last decade, such as Ocean NanoTech, Nanoprobes, US Research Nanomaterials, Miltenyi Biotec, micromod Partikeltechnologie GmbH, and nanoComposix, etc. In this paper, we report the physical and magnetic characterizations on iron oxide nanoparticle products from Ocean NanoTech. Standard characterization tools such as Vibrating-Sample Magnetometer (VSM), X-Ray Diffraction (XRD), Dynamic Light Scattering (DLS), Transmission Electron Microscopy (TEM), and Zeta Potential Analyzer are used to provide magnetic nanoparticle customers and researchers with an overview of these iron oxide nanoparticle products. In addition, the dynamic magnetic responses of these iron oxide nanoparticles in aqueous solutions are investigated under low and high frequency alternating magnetic fields, giving a standardized operating procedure for characterizing the MNPs from Ocean NanoTech, thereby yielding the best of magnetic nanoparticles for different applications.
