NanoLight: light and matter at the nanoscale

The Project

Invisibility cloaks are related to solar energy new trends to fight global warming. And medieval rose windows can explain some aspects of nanomedicine, early diagnosis and noninvasive phototherapies. How? All these phenomena share a common ingredient: the interaction of light with nanomaterials. Come and fabricate your own nanoparticles and use them on a series of photonic challenges involving ultimately the interaction of light with living cells, at the core of cancer diagnosis and therapies.

Light usually refers to the visible part of the electromagnetic spectrum, plus the infrared (heat) and the near ultraviolet. Light waves, as any other electromagnetic radiation, transport energy and momentum. Being able to control the interaction of light with matter at the nanoscale allows the construction of materials to concentrate heat in very small places, or select specific wavelengths (colors) of an incoming white radiation. Roughly speaking, we can engineer materials to deal with energy and information with accuracy and precision unreachable before the arrival of nanotechnology.

In this course, we have focused on the interaction of light with metallic nanoparticles. You will understand how the free electrons on these nanoparticles resonate with the electric field of light, and how this resonance depends on the composition and more critically on the size and form of the nanoparticles. You will then be asked to solve a series of chained challenges –which go from aligning an optical experiment to being part of the process of nanofabrication– with the ultimate goal of controlling and measuring heat generation at the nanoscale.

A potential application of this technique is photothermal cancer therapy, in which cancerous cells are destroyed with concentrated heat, but during your stay at ICFO you will be also exposed to many other uses and features of the interaction of light and matter at the nanoscale, dealing with nanomedicine, solar cells, new materials, and even quantum information.

Romain Quidant

Romain Quidant received his PhD in Physics in 2002 from the University of Dijon (France). Since then he has worked in Barcelona at ICFO in the field of nanoplasmonics. In 2006, he was appointed junior Professor and junior group leader of the Plasmon NanoOptics group at ICFO. In 2009, he became ICREA Professor and tenure group leader at ICFO. His research focuses on the study of the optical properties of metal nano-structures, known as nanoplasmonics. 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 the use of light and heat control at the nanometer scale for biomedical applications, including early detection and less invasive therapies. His research trajectory has been acknowledged by several national and international prizes among which the Fresnel prize from the European Physics Society (2009), the prizes of the City of Barcelona (2010) and the Fundació Príncep de Girona (2011), the 2012 ICO prize from the International Commission for Optics and more recently the 2015 national prize for research (in the category young talent). In 2010 he obtained a Starting Grant from the European Research Council (ERC) that was complemented by an ERC Proof-of-concept grant in 2011. In 2015, Quidant was awarded an ERC Consolidator Grant and another Proof of Concept grant.
