Séminaire – C. Pin

1 juillet 2019 @ 10 h 30 min

Le chercheur C. Pin de la Research Institute for Electronic Science de l’université de Hokkaido au Japon présentera un séminaire intitulé :

Optical manipulation of nanoparticles using plasmonic antennas and glass capillaries

Ce séminaire aura lieu lundi 1er juillet, dans la salle D115 du bâtiment Sciences Mirande, à 10h30.

Résumé : Light can provide an efficient and contactless way to trap, manipulate, and sort micro- and nano-objects in liquid colloidal solution. However, the optical manipulation of nanoparticles requires nanoscale light confinement. While plasmonic nanogap antennas allow for studying light-matter interactions at the single nanoparticle level, glass nanocapillaries provide a promising way to maximize the interaction between a guided light beam and an ensemble of nanoparticles. In my talk, I will first present my recent work on the optical trapping and the deposition of nanoparticles
using gold nanogap antennas. In a second part, I will show how fluorescent nanodiamonds can be propelled inside a tapered glass capillary and discuss the possibilities offered by this technique in optical sorting applications
