Title
How bio filaments change shapes of soft membrane vesicles
Abstract: Membrane vesicles are often used to understand the physics of shape change in real cells. We will discuss growth of narrow membrane tubes from a vesicle. Artificial membrane tubes are commonly pulled out from phospholipid vesicles using external force through laser tweezers or processive motor proteins. Recent examples have emerged where tubes spontaneously grow from vesicles coated with bioactive filaments in the presence ATP. We show how topology of the vesicle surface its local curvature and active forces due to the filaments cause the soft vesicle to deform.Bio-sketch: Anirban Sain did his PhD in 1999 from IISc Bangalore followed by post-doctoral work at Simon Fraser Univ. (1999-2001) Univ. of Waterloo (2001-2002) and McGill Univ. (2002-2003). In between he did industrial research at Hindustan Lever R & D in 2001. Since then he has been at IIT Bombay where his research interests involve various problems of nonequilibrium statistical physics and biophysics.
