ABSTRACT

Arthur Ashkin won the Nobel prize last year for his work on optical tweezers; however, those conventional optical tweezers are limited to objects that are >100 nm in size. This talk will review our work on nanoaperture optical tweezers that can trap particles down to the single digit nanometer size, including proteins. I will describe how to measure the low frequency Raman modes of these particles (including proteins and DNA fragments) with high spectral resolution, as well as the THz dynamics of nanoparticles. I will emphasize recent developments in nanofabrication and some exciting biophysical problems we are studying.


Bio: Reuven Gordon holds a Canada Research Chair in Nanoplasmonics and a Professor position in the Department of Electrical and Computer Engineering. In 2009, Dr. Gordon was a visiting Professor at the Institute for Photonic Sciences (ICFO, Barcelona, Spain). He has received a Canadian Advanced Technology Alliance Award (2001), an Accelerate BC Industry Impact Award (2007), an AGAUR Visiting Professor Fellowship (2009), the Craigdarroch Silver Medal for Research Excellence (2011), and the Facutly of Engineering Teaching Award (2017). He is a Fellow of the Optical Society of America (OSA), a Fellow of the Society for Photographic Instrumentation Engineers (SPIE), and a Fellow of the Institute for Electrical and Electronic Engineers (IEEE).
