    Petia Vlahovksa - ME 512 Seminar - "Electromechanics of Biomimetic Bilayer Membranes"

    McCormick - Mechanical Engineering

    3:00 PM L211 Technological Institute

    EVENT DETAILS

    ABSTRACT: Living cells maintain electric potential difference across their plasma membrane. Changes in the transmembrane electric field are biologically important signals in physiological processes such as electric-field-directed cell migration in development and regeneration. Pulsed electric fields are used to open pores in the membrane, which enable the delivery of material inside
    the cell, e.g. for gene transfection.
    I will present our theoretical and experimental work on the deformation and stability of biomimetic membranes (bilayers assembled from lipids or polymers) in electric fields. Giant vesicles exposed to DC pulses adopt peculiar drum-like shapes and may collapse. Our experiments suggest that the edge separates porated (conducting) and intact (insulating) regions of the membrane. The time dependence of the edge location can serve as a quick method to estimate the critical voltage for membrane poration. Electrohydrodynamic analysis of the collapse dynamics shows that membrane conductance and asymmetry in the embedding electrolyte solutions destabilize the interface; membrane viscosity slows down the growth of the instability. In the case of multicomponent membranes, electric fields induce reversible phase separation.

    BIOGRAPHY: Petia Vlahovska received a PhD in chemical engineering from Yale and MS in chemistry from Sofia University (Bulgaria). She was a postdoctoral fellow in the Membrane Biophysics Lab at the Max Planck Institute of Colloids and Interfaces and an assistant professor in the Thayer School of Engineering at Dartmouth College. She joined the School of Engineering of Brown University in Fall, 2010. Her research interests are in fluid dynamics, membrane biophysics, soft matter, and nonlinear physics. Dr. Vlahovska is the recipient of NSF Career Award and David Crighton Fellowship.
