Celia Toyos-Rodríguez is a Postdoctoral Researcher at the University of Antwerp, working on the development of photoelectrochemical based sensors. She has a PhD in Analytical Chemistry from the University of Oviedo, performed at the NanoBioAnalysis group funded by a National Research PhD Grant from the Spanish Ministry of Science and Innovation (MICINN). Her research interests include the use of nanomaterials, as electrocatalytic nanoparticles and nanopores, for the development of electrochemical and photoelectrochemical biosensors, especially for the detection of biomarkers related with neurodegenerative and infectious diseases.
