Title: Bioplasmonics: designing novel nantools for biosciences
Session: Monday 5 October, 13:30


Two decades of extensive research in the field of plasmonics have shown that metallic nanostructures supporting localized surface plasmon (LSP) resonances stand as ideal systems to control light and heat on the nanometer scale. These unique physical properties offer new opportunities in the field of biotechnologies. In this talk we review our recent activities in the development of novel tools for biosciences based on metallic nanostructures. We first present an integrated analytical platform that combines the sensing capability of plasmonic antennas with advanced microfluidic technologies for the label-free multiplexed detection of protein cancer markers in blood. Our platform enables parallel, real-time detection of several markers from a single drop of human serum with a sub-ng/ml sensitivity and is currently tested for early diagnosis and treatment monitoring. Next we show plasmonics also enables to push the limits of nano-manipulation by developing nano-optical tweezers capable to trap and manipulate non-invasively nanometer-sized specimens including biomolecules.



Romain Quidant carries out his research at ICFO - The Institute of Photonic Sciences in Barcelona where he leads Plasmon nano-Optics group. His research focuses on the study of the optical properties of metal nano-structures, known as surface plasmons. The activities of his group cover both fundamental and applied research. The fundamental part of his work is mainly directed towards enhanced light/matter interaction for quantum optics. From a more applied viewpoint, his group investigates news strategies to control light and heat at the nanometer scale for biomedical applications, including early detection and photothermal therapy of cancer
