Nano-bio Interface

Archived Research

This work is to understand the mechanisms and conditions under which engineered nanomaterials can cause disruption of, and passive transport through, simplified model of artificial cell membranes, namely lipid bilayers. We believe that under some conditions engineered, ENMs, can passively translocate across, and cause nanoscale defects in lipid membranes, which plays a role in cellular toxicity.
