César Pascual-García graduated in Solid State Physics at the Universidad Autónoma of Madrid in Spain with a dissertation of Electronic optical transitions in III-V semiconductors. He obtained his PhD in Condensed Matter Physics in 2007 at the Scuola Normale Superiore of Pisa in Italy with the Thesis “Low lying excitations of few electrons quantum dots”. After having an education base on the study of fundamental phenomena of electron correlations in semi- and super- conductor materials, his activities shifted to topics in applied biology working as Scientific Officer at the Institute for Health and Consumer Protection of the European Commission. Currently he is an ATTRACT fellow and Lead Research Scientist at the Luxembourgish Institute of Science and Technology where he is leads the activities for electrochemical sensors and actuators for medicine applications at the Materials Research and Technology department. His current research focus is molecular diagnostics and their applications in personalized medicines.

Bio-sensing for early diagnostics and to facilitate clinical-decisions is a key-enabling technology for the implementation of next generation. In the last decades, several devices for molecular diagnostics based in the manipulation of genetic material (DNA, RNA…) have validated this concept. The next step is demanding tools for the detection of molecules beyond nucleotides. Field effect transistors (FETs) emerge as one of the candidates for label free sensing, in fact, nano-FETs have shown limits of detection in the femtomolar range. However no clinical applications are currently available. The first drawback is the balance between the optimisation for diffusion-limited processes and reliability, which has made that multiplexing for personalised medicines has low confidence levels and hampers mass production to lower the cost of Point of Care devices. The second limitation is the ionic screening in biological conditions. Many assays using label free sensing measure end-point assays after cleaning and using low ionic strength electrolytes. This decreases the relevance of the measurements and hinders the possibility to access the kinetic information of the molecular binding. We will present a new design of FET for label free sensing using a high aspect ratio FinFET that addresses appropriately all these questions.
