Title: Passive permeation through biological membranes
Abstract: Passive permeation is a spontaneous translocation process in which molecules pass through membranes unassisted by channels or pumps. I will describe computer simulations and experiments of passive permeation processes. The following questions will be addressed: (i) Which charged molecules (positively or negatively charged) permeate passively more readily through biological membranes? (ii) Can we measure and adjust electric fields inside membranes by manipulating the membrane composition? (iii) Can we model the permeation of water molecules through biological membranes?
Research conducted in collaboration with Alfredo Cardenas, Lauren Webb, Rebika Shrestha, and Cari Anderson.
