The Walker Department of Mechanical Engineering at The University of Texas at Austin welcomed Professor Peer Fischer of the Max Planck Institute at the University of Stuttgart, Germany as a Cockrell School of Engineering Endowed Lecturer to share “Nanorobots for Biomedical Applications and Ultrasound for the Instant Assembly of Cellular Structures.”
Inspired by Richard Feynman’s famous lecture “There’s plenty of room at the bottom,” researchers are striving to build synthetic motors, machines, and robots ‘bottom up’ from the nanoscale. However, despite progress in crafting static structures of increasing complexity, truly functional dynamic machines are still in their infancy. Building and powering artificial structures that operate at the microscale is very challenging, as it is generally not possible to translate actuation mechanisms and design-concepts from the macro- to the nanoscale. At this scale different physical phenomena are important and there are no ready-made motors and no off-the-shelf parts. In this talk I will describe the fabrication and operation of “nanobots” that can be controlled in fluids with magnetic fields. A focus of the lecture is the physics and chemistry needed to enable their propulsion through complex biological tissues. Another means of power transfer is via sound fields. However, existing technologies to manipulate sound have been lacking. I will discuss new means of shaping ultrasound using the acoustic hologram and describe how it can be used to obtain the most sophisticated sound fields to date. The hologram permits the directed assembly of cells and for “one-shot” parallel 3D fabrication.
