“Molecularly Imprinted Polymers and Optical Fiber Sensors for security applications“
In the last years, the classic geometries of sensors based on Surface Plasmon Resonance (SPR) in silica optical fibers are adapted and borrowed for Plastic Optical Fibers (POFs), thus representing a simple approach to low cost plasmonic sensing. POFs are particularly advantageous due to their excellent flexibility, simple manufacturing and handling procedures, great numerical aperture, large diameter, furthermore to the fact that plastic is able to withstand smaller bend radii than glass. Should receptors be used for Bio/Chemicals detection, this low cost SPR-POF platform can be applied in different fields: industrial applications, medical diagnostics, environmental monitoring, food safety and security. For example, by using a Molecularly Imprinted Polymer (MIP) receptor, we have presented experimental results on the selective detection of trinitrotoluene (TNT), significant in security applications. In particular, two POF-MIP different sensor configurations for TNT detection are presented. These sensor configurations are based on the same MIP receptor, one, combined with a Surface Plasmon Resonance platform and, another one, with a Localized Surface Plasmon Resonance platform, both made in D-shaped POFs.
Nunzio Cennamo was born in Italy in 1975. He graduated in electronic engineering in 2002, then took the Ph.D. degree in electronic engineering in 2005, both at the Second University of Naples, located in Naples, Italy. He is currently a post-doc at the Department of Engineering at University of Campania “Luigi Vanvitelli”, Aversa, Italy. His research interests include the design and fabrication of optical fiber sensors, chemical sensors, biosensors and optoelectronic devices. He published more than 80 international journal and conference papers and 3 patents. He is an invited speaker in several international conferences.
He is a reviewer for several technical journals, Member of the Technical committee of “IEEE Sensors Applications Symposium (SAS 2017, SAS 2018)” and of “The Third International Conference on Advances in Sensors, Actuators, Metering and Sensing” (ALLSENSORS 2018), several times Guest Editor of Sensors (MDPI) and Member of the Editorial Board of International Journals: “International Journal of Nanomaterials, Nanotechnology and Nanomedicine”, “Journal of NanoScience and NanoMedicines” and “Journal of Biosensors & Bioelectronics”. He is an Organizer/Chair of the Special Session on “Optical fiber sensors in measurement systems and their application”, in the IEEE (I2MTC) International Instrumentation and Measurement Technology Conference 2018.
