Seminar on “Living Machines”
Department of Biomedical Engineering organized a technical seminar on “Living machine” on 22nd Nov 2017. The talk was presented by Dr. Taher Saif, Professor, Department of Mechanical Science and Engineering, the University of Illinois at Urbana-Champaign. During the talk, he described how a “living machine” may emerge from an interaction between the living cells and the micro-nano scaffolds. The elementary micro machine consisting of a soft slender string and rat cardiomyocytes. These cells interact with the string as well as with each other and beat in synchrony as a single actuator. This living actuator bends the string, and a bending wave propagates from the actuator site towards the end, as a bending of a sperm. This artificial machine thus swims in fluids as the engineered living swimmer. These swimmers might be used in vivo for autonomous intelligent drug delivery.
Dr. Taher Saif received his BS and MS degrees in Civil Engineering from Bangladesh University of Engineering and Technology and Washington State University respectively in 1984 and 1986. He obtained his Ph.D. degree in Theoretical and Applied Mechanics from Cornell University in 1993. He worked as a Post Doctoral Associate in Electrical Engineering and the National Nanofabrication Facility at Cornell University during 1993 – 1997. He joined the Department of Mechanical Science and Engineering at the University of Illinois at Urbana-Champaign during 1997. He is currently the Gutgsell Professor in the department. His current research includes tumor micro-environment, mechanics of neurons and cardiac cells, development of biological machines, and electro-thermo-mechanical behavior of nano-scale metals and semiconductors.
