A biosensor device is defined by its biological or bioinspired receptor unit with specificities toward specific bio analytes. Analytes are often from biological origin like DNA, proteins generated from the immune system (antibodies, antigens), receptors at the cell membranes, entire living organisms (viruses, bacteria or blood cells) or simple molecules involved in a physiological process like glucose. Analysis of pollutants is also of our interest.
Nanotechnology could revolutionize health care by enabling more efficient diagnostic devices. In our lab, we develop biosensing technologies for point of care and medical diagnosis taking advantage of optical and photonic properties of nanoparticles.
