Michel Meunier plenary talk: A New Plasmonics Enhanced Ultrafast Laser Multi-Nanoscapel

Presented at SPIE Photonics West 2014

17 March 2014, SPIE Newsroom. DOI: 10.1117/2.3201403.22

Michel Meunier, Ecole Polytechnique de Montréal (Canada)In his plenary talk, "A New Plasmonics Enhanced Ultrafast Laser Multi-Nanoscapel," SPIE Fellow Michel Meunier of Ecole Polytechnique de Montréal (Canada) introduces a new technique for performing nanosurgery in living cells using a laser multi-nanoscapel. Irradiating plasmonics nanostructures by an ultrafast laser beam produces highly localised processes on the nanoscale in the biological surrounding medium, yielding to the nanosurgery of cells. These nanoparticles could be functionalised to target specific biological entities, thus performing multiple targeted surgeries on the nanoscale.

As an example, the laser multi-nanoscapel was employed to perform gene transfection in living cell with an optoporation efficiency as high as 70%. A complete physical model was developed to determine the basic mechanism underlying this new nanosurgery process. The laser multi-nanoscapel shows promises as an innovative tool for fundamental research in biology and medicine as well as an efficient alternative nanosurgery technology that could be adapted to therapeutic tools in the clinic.

Michel Meunier obtained his PhD in materials science from the Massachusetts Institute of Technology (MIT) in 1984 and has been a professor of engineering physics at École Polytechnique de Montréal since 1986. in 2001, he was awarded a Canadian Research Chair to perform research and innovation in laser micro/nano-engineering of materials and plasmonics for nanotechnology and biomedical applications. He is Fellow of SPIE, OSA and the Canadian Academy of Engineering. He has a research group of ~20 people and has published over 330 papers.
