The 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. Funded currently by the NIH, NSF and NASA, our goal is the creation of technologically-relevant platforms including micron-scale colloidal-based devices and microbots for biomedical treatment.
