Prof. Michael McAlpine, Princeton University. He will give a talk entitled "BIONIC NANOMATERIALS".ABSTRACT: The development of a method for interfacing high performance devices with the human body could yield breakthroughs in regenerative medicine, prosthetics, and human-machine interfaces. Yet, most high quality inorganic materials are hard and brittle, and their crystallization generally requires high temperatures for maximally efficient performance. These properties render the corresponding devices incompatible with soft tissue.
Nanotechnology provides a route for overcoming these dichotomies, by altering the mechanics of materials while revealing new effects due to size-scaling. In this talk, I will focus on vital areas for biointerfacing nanodevices: 1) graphene nanosensors for ubiquitous detection, and 2) piezoelectric PZT nanoribbons for bioelectromechanical energy harvesting. Our approach involves the following key
steps: first, new nanomaterial synthesis or fabrication; second, fundamental studies of novel properties; and finally, interfacing these materials with cells and tissue. I will also present a future vision of bionic systems in which the electronics and biology are seamlessly interwoven in 3D. The novel properties of nanomaterials coupled with “living” platforms may enable exciting avenues in fundamental studies and bioMEMS applications, including the creation of augmented bionic organs.
