Dr. Sibani Biswal is an Associate Professor at the Department of Chemical and Biomolecular Engineering at Rice University in Houston, TX and leads the Soft Matter Engineering Laboratory. She has a B.S in chemical engineering from Caltech (1999) and a Ph.D. in chemical engineering from Stanford University (2004). She then was a CPRIT postdoctoral fellow at UC Berkeley (2004-2006). She is the recipient of an ONR Young Investigator Award (2008), National Science Foundation CAREER award (2009), the Southwest Texas Section AICHE Best Fundamental Paper Award (2014), 2015 Abu Dhabi International Research and Development Conference (ARDAC) Innovation Award, and George R. Brown Award for Superior Teaching (2015).
“Directed Colloidal Assembly with DNA and Magnetic Fields”
One of the most exciting areas in colloid research is the control of interparticle interactions to generate new structures. The ease of tuning interactions, size, shape and composition has made these nano- and micrometer sized particles appealing probes for a number of fundamental studies. Recent work has focused on the use of colloidal particles that can act as models for studying the fundamental phenomena of atomic systems. The self-assembly of these “colloidal atoms” has led to investigations of the dynamics of chemical transformations such as nucleation or phase transitions. I will describe the application of a unique colloidal assembly system, with an isotropic interaction potential, to study material properties, such as phase transitions and melting. Magnetic filaments comprised of magnetic particles linked with DNA offer a method to probe dynamics of semiflexible filaments. Additionally, studies on out of equilibrium phenomena will offer novel dynamic behavior, such as colloidal microscale swimmers. Our results promise to open up new insights into magnetically actuated 2-D materials.
