Sensors Webinar | Nanotechnology Applications in Sensors Development
the chair
Nanotechnology development has offered the possibility to choose among a very large class of nanostructured elements to expand the use of optical methods for sensing applications. The miniaturization of matter provides interesting and unique optical properties, enabling the development of new sensing schemes and devices characterized by an increased specificity and sensitivity, reliability, and adaptability, as required for innovative applicative approaches for the qualitative and quantitative determination of analytes of interest in pharmaceutical research, medical diagnostics, environmental monitoring, agriculture, industry, and food safety and security.
This webinar offers the opportunity to meet researchers involved in the field of nanotechnology applications for optical sensing to discuss some topics together. In particular, we would like to focus our attention on the improvements due to the use of nanostructured substrates in Raman spectroscopy and the results offered by the use of hybrid nanoparticles in intracellular sensing and therapy.

Nanotechnologies enable the development of new sensing schemes and devices characterized by increased specificity and sensitivity, reliability, and adaptability, as required for innovative applicative approaches for the qualitative and quantitative determination of analytes. Our webinar session includes two contributions devoted to some applications of nanotechnologies to optical sensing. The former talk (“Nanotechnology in sensing biomolecules by vibrational spectroscopy” by Dr. Ines Delfino) presents fundamental aspects related to the working principles, design, and fabrication of substrates for Surface-Enhanced Raman Spectroscopy (SERS) that result extremely useful when sensing very small quantities of analytes is required. The second one (“Hybrid nanoparticles for intracellular sensing and therapy” by Dr. Ilaria Rea) describes using porous biosilica-based NPs for biomedical applications. The NPs are derived from diatomite, a material of sedimentary origin formed from the remains of diatom skeletons. A hybrid nanosystem constituted by diatomite NPs covered by gold NPs acting as SERS substrates is proposed for simultaneous intracellular drug sensing and delivery.
