The NanoB2A group is a multidisciplinary research team led by Prof. Laura M. Lechuga. We are physicists, engineers, chemists, and biologists working in the broad field of Nanobiotechnology. Our motivation is to develop new and cutting-edge biosensor nanotechnologies using photonics, one of the key technologies of the 21st century, to promote and boost healthcare and well-being for our society.
Our research focuses on the development of photonic point-of-care biosensors and their employment in clinical, biomedical, and environmental areas. We mainly exploit Nanoplasmonics and Silicon Nanophotonics technologies to accomplish integrated biosensing systems for the label-free, real-time, and multiplexed analysis at the point of care. Our activity encompasses the entire process of generating new biosensor devices, including fundamental research and theoretical design, nanofabrication, surface biofunctionalization, lab-on-a-chip integration, and their final validation in real scenarios.
NanoB2A group is established at the Catalan Institute of Nanoscience and Nanotechnology (ICN2), in Barcelona (Spain), belonging to the CERCA network of Catalan Research Institutes and integrated in BIST (Barcelona Institute of Science and Technology). The NanoB2A belongs as well to the Spanish National Research Council (CSIC) and the Networking Center on Bioengineering, Biomaterials and Nanomedicine (CIBER-BBN).
A new article introducing our nanophotonic device has been recently published in the BioOptics World section of Laser Focus World, a monthly trade magazine for optics industry professionals.A nice and comprehensible description of how our device works and its potential for diagnostics at the point of need.

The Unit of Biodetection belonging to the U4- NANBIOSIS has been recently upgraded with new optics and microfluidic components to improve its performance and increase its competitiveness with other similar equipment in the market.
The Unit of Biodetection, a Surface Plasmon Resonance (SPR) biosensor, available at the Unit is a highly sensitive device that allows the monitoring of biomolecular interactions in a real time label-free configuration.The optical device is based on the detection of the refractive index changes occurring in the sensing surface (i.e. metallic surface), which in turn can be related to mass changes as those occurring as a result of binding/desorption processes. With this actuation, some components have been updated (i.e. flow injection pimps, light sources, and spectrophotometer for signal output, among others) in order to increase the performance of the current design.
The ERDF funding was also used to update the UV/O3 Cleaner of the Biodeposition Unit belonging to the same NANBIOSIS Unit 4
At the ICN2, together with Phantoms Foundation, we are organizing the first online conference about COVID19 pandemics. The Biosensors for Pandemics Conference will be streamed worldwide on May 6th, joining top international researchers to discuss how new nanotech diagnostic systems can help in health emergency situations.
Prof. Laura M. Lechuga will give a Keynote presentation about the CoNVat project and how our advanced nanobiosensing platforms are being developed for point-of-care diagnostics and surveillance of coronavirus.
