Roberto Rella, Physicist, from 2001 Senior Researcher of the National Research Council at the Microelectronics and Microsystems Institute (IMM-CNR) unit of Lecce – Italy. Adjunct Professor of material’s science and technology at the University of Salento. The research activity relates to the optimization of prototypes of new devices for optoelectronic sensing and biosensing applications. Optics and optochemical sensors with new organic and inorganic material systems like metal oxide semiconductors, organic microcycles, conjugated polymers, dots and rods of metal oxide semiconductors, gold nanoparticles, organic/inorganic multilayer systems. Deposition in thin-film form by using various preparation techniques, self-assembly, spinning, thermal evaporation, self-assembly and Langmuir–Blodgett technique. The emphasis of this work is on the fabrication of electronic devices incorporating these layers in the realization of chemical (gas, vapour and liquid) sensors, self-organized structures, and nanoscale devices. Analysis of the sensing performances and optimization of the sensing parameters. Development and application of surface-sensitive spectroscopic techniques such as surface plasmon resonance (SPR) imaging, magneto-plasmonic SPR, localized SPR. Chemical modification of metal surfaces for adsorption-based biosensors (BIOMEMS)
