David MarrThe controlled assembly of colloidal particles has received significant attention because of their potential application as nano- and micro-structured materials. To vary their structure and behavior, we employ external fields, including applied time-varying electromagnetic, electric, and magnetic fields. One technique that we use to great extent is optical trapping in which a “tractor beam” like approach, using a focused laser, is used to manipulate individual cells and colloidal particles. Funded in recent years by the NIH, NSF and NASA, our goal is the creation of technologically-relevant platforms including micron-scale colloidal-based devices as well as optical-based cell sorters and stretchers for bioanalysis and microbots for biomedical treatment.
