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.

美国国家科学基金会化学部的分析和表面化学项目支持宾夕法尼亚州立大学化学系Mary Elizabeth Williams教授的研究项目。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合的磁操纵和选择性分离”的项目。具有纳米尺度尺寸的小颗粒具有独特的性质，使它们在生物医学、催化和传感方面很有趣。威廉姆斯的研究小组对小的磁性颗粒特别感兴趣，这些颗粒可以用磁铁牵引和捕获。当这些粒子以化学方式连接在一起时，有望形成具有改进性能的新材料，用于上述应用。这个研究项目的重点是基于粒子的大小、磁性和连接粒子的数量，通过高水平的控制来操纵和拉动粒子。该研究为纳米科学和纳米技术这一高度跨学科和前沿的研究领域的本科生、研究生和博士后研究人员提供了极好的培训机会。
