Magnetic Manipulation and Selective Isolation of Nanoparticles and Nanoparticle Assemblies

NSF化学部的分析和表面化学计划正在支持宾夕法尼亚州立大学化学系玛丽·伊丽莎白·威廉姆斯教授的研究计划。威廉姆斯教授和她的学生专注于一个名为“纳米颗粒和纳米颗粒组件的磁性操纵和选择性分离”的项目。具有纳米尺度的小颗粒具有独特的性质，使它们在生物医学、催化和传感方面具有重要意义。威廉姆斯的研究小组对微小的磁性颗粒特别感兴趣，这种颗粒可以用磁铁拉动和捕获。当这些粒子化学连接在一起时，这些粒子有望形成性能更好的新材料，用于上述应用。这一研究项目的重点是根据颗粒的大小、磁性和连接的颗粒数量，对颗粒进行高水平的磁性操纵和拉动。这项研究为纳米科学和纳米技术的高度多学科和尖端研究领域的本科生和研究生以及博士后研究助理提供了极好的培训机会。

The Analytical and Surface Chemistry Program of NSF Division of Chemistry is supporting the research program of Professor Mary Elizabeth Williams in the Department of Chemistry at The Pennsylvania State University. Professor Williams and her students focus on a project titled "Magnetic Manipulation and Selective Isolation of Nanoparticles and Nanoparticle Assemblies." Small particles that have nanometer scale dimensions have unique properties that make them interesting for biomedicine, catalysis and sensing. The Williams research group is particularly interested in small magnetic particles, which can be pulled and trapped using magnets. When these are chemically linked together, the particles are expected to form new materials with improved properties for the above applications. This research project focuses on magnetically manipulating and pulling particles with a high level of control based on their size, magnetic properties, and number of linked particles. The study provides excellent training opportunities for undergraduate and graduate students and postdoctoral research associates in the highly multidisciplinary and cutting edge research field of nanoscience and nanotechnology.
