“Positive and Negative Chemotaxis of Enzyme-Coated Liposomes”
Ambika Somasundar, Pennsylvania State University
Ambika Somasundar is a 4th year chemical engineering graduate student working with Dr. Ayusman Sen and Dr. Darrell Velegol at Penn State. Her research focuses on making colloids move and understanding why they move. In this seminar, Ambika will discuss positive and negative chemotaxis (i.e., directional migration in response to chemical signals) of liposomal protocells based on the interplay between positive enzymatic catalysis-induced chemotaxis and solute-phospholipid interaction-based negative chemotaxis. Controlling the extent of chemotaxis holds considerable potential for designing cell mimics and delivery vehicles that can reconfigure their motion in response to environmental conditions.
