Monitoring of a set of metabolites (e.g., glucose, lactate) and ions (e.g., potassium) in human fluids is of significant importance in medicine. Instrumentation designed for a timely multi-sensing should be able to perform several measurements from a small volume sample. Consequently, the development of a tiny device is a crucial requirement. Electrochemical miniaturized devices are particularly advantageous because of the inexpensive and reproducible fabrication procedures and the simple analytical measurements. A continuing challenge in their fabrication is the detection of metabolites and ions in the physio-pathological concentration range. Modifying electrodes with nanostructures can solve this issue as due to their high electrocatalytic activity and large surface-to-volume ratio. Tailored nanostructuration methods are extremely important to boost the sensor sensitivity, selectivity and stability over time. In this talk I will illustrate novel protocols to modify electrodes with carbon and metal nanostructures without the use of binders that can mask the nanomaterial promising properties and can compromise the time-stability of the nanostructures in aqueous environment. Carbon nanomaterials were selectively deposited on electrodes by CVD and nanoporous metal layers by template-free electrodeposition processes. Both nanostructuration approaches generated electrodes with significantly enhanced detection performance as compared to the bare counterparts for sensing human metabolites and ions.

Short Bio: Irene Taurino was born in Italy in 1986. She received the BSc and the MSc degree in Biomedical Engineering both cum laude from Politecnico di Torino (Italy) in 2008 and 2010, respectively. She also got the MSc degree in Biomedical Engineering from Politecnico di Milano (Italy) in 2010. She received the PhD degree in Microsystems and Microelectronics from the École Polytechnique Fédérale de Lausanne (EPFL) in 2015. She is currently a Post-Doctoral Researcher in the Integrated System Laboratory, EPFL , working under the supervision of Prof. G. De Micheli and Dr S. Carrara. The focus of her research is the development of new methods to selectively and efficiently integrates nanomaterials and nanoporous layers onto electrodes of multipanel electrochemical biosensors for improving the detection performance towards metabolites and ions. Her PhD Thesis was ranked in the list of the 8 Best Theses of EPFL for 2014/2015. She recently obtained a Special Distinction from the selection committee for her PhD research work. She published 1 book chapter, 18 journal papers (12 as first author) and 8 conference papers (3 as first author). She also filled 1 patent in the field.
