Conventional top-down nanofabrication, over the last six decades, has enabled almost all the complex electronic, optical and micro-fluidic devices that form the foundation of our society. Parallel efforts, exploring bottom-up self-assembly processes, have also enabled design and synthesis of structures like quantum dots, carbon nanotubes and unique bio-molecules that possess technologically relevant properties unachievable top-down. “Hybrid nanostructures” have mostly failed to get over technical integration hurdles. This talk from Samsung Forum, Professor Ashwin Gopinath discusses DNA origami as a molecular adaptor to modularly position and orient bottom-up nano-components (like quantum dots, light emitters and proteins) within top-down nanofabricated devices. Dr. Gopinath presents his vision of how DNA origami bridges top-down and bottom-up nanofabrication and can enable a range of highly transformative, and functional, devices including single-photon sources, single-molecule counters, economical large-area nanotexturing, and a modular molecular interface between biology and solid-state.

About the Speaker

Ashwin Gopinath joined MIT in Jan 2019 as an assistant professor in the Mechanical engineering department where his lab is working on projects at the intersection of molecular self-assembly, surface- chemistry, top-down nanofabrication and synthetic biology. Dr. Gopinath received his Phd in electrical engineering from Boston University, in 2010, for his work on understanding light transport in disordered media. His research involves developing tools to organize single molecules/atoms using standard micro-fabrication tools in the service of developing high-throughput molecular diagnostic platforms, components for quantum computation and more-than-moore devices. Dr. Gopinath has co-authored 21 papers in journals like Nature, Science and PNAS as well as received several awards, most recent of which is the 2017 Robert Dirk Prize in Molecular programming for his seminal contributions in merging DNA nanotechnology with conventional semiconductor nanofabrication.
