In this talk, we will explore the ability to manipulate and detect magnetic nanoparticles (MNP) at chip level, and how it is revolutionizing integrated miniaturized laboratories. The choice of magnetoresistive (MR) sensors results from their outstanding achievements in many areas, from reading magnetic bits for information storage (magnetic hard disk recording) to nanoparticle detection in biomedical platforms or neuronal synaptic activity measurements in neurosciences. Irrespective of the application, the integration of MR sensors and MNP offers quantitative and qualitative functionality to biosensing (e.g. comparing to optical or chemical methods). Moreover, magnetic and electromagnetic actuation are becoming extremely attractive components to precisely transport, mix, manipulate, and concentrate (sort, separate, purify, and detect biomolecules) MNP for binding and analysis. The ability to match these distinct technologies is a growing and not much explored route to provide ultra-compact heterogeneous integration of hybrid systems within multifunctional chips. However, the challenges of handling liquids and MNP over a chip combine with those for miniaturization of microelectronics. When these are overcome, the result is an integrated microfluidic system with added capabilities, able to answer to demands in biomedicine and drug delivery.
Desigualdades de Bell y el inicio de la segunda revolución cuántica

En octubre de 2022 Alain Aspect, John Clauser y Anton Zeilinger recibieron el premio Nobel de física "por sus experimentos con fotones entrelazados que establecieron la violación de las desigualdades de Bell, y por su calidad de pioneros en la ciencia de la información cuántica" . En este coloquio hablaremos sobre algunos de sus logros y cómo estos influyeron en la visión que tenemos de la naturaleza. Además, pondremos en contexto de qué modo dieron lugar a lo que hoy se conoce como la segunda revolución cuántica.

The James Webb Space Telescope (JWST), the successor of the famous Hubble Space Telescope, has finally launched and has started doing science! The Webb Telescope, a 6.5m infrared telescope, is without a doubt one of the most complex machines ever built by humanity and the largest telescope ever sent to space. Thanks to Webb, we now have the capacity to see farther than ever in our Universe, peer through the cosmic dust sprinkled throughout galaxies and discover and study new alien worlds. This project is an international collaboration between NASA, the European Space Agency and the Canadian Space Agency. In addition to contributing the FGS/NIRISS instrument, Canada and its astronomers are already some of the first to use the telescope and have already begun producing groundbreaking science thanks to its revolutionary data. As the first few images and bits of data start to trickle in, you will learn about some of Webb's very first exciting discoveries and what this mission means for the future of space astronomy.

El desarrollo exitoso de la fotosíntesis artificial requiere encontrar nuevos materiales capaces de recolectar eficientemente la luz solar y catalizar reacciones de generación de hidrógeno y reducción de dióxido de carbono. Las nanopartículas plasmónicas o dieléctricas son potenciales candidatas para estas tareas, debido a su capacidad para confinar la energía solar en regiones moleculares. Mediante el empleo de materiales estructurados artificialmente (metamateriales), coloides plasmónicos híbridos, nano-resonadores dieléctricos o nanoantenas metálicas, mostraré algunos de nuestros esfuerzos más recientes para convertir energía solar en energía química controlando y optimizando las interacciones luz-materia [1-7].
