Photonics and Plasmonics: New Challenges for Optical Nanostructured Materials in Sensing

In the last decade, new technologies have undertaken an extraordinary development, based not only on new materials and new processes but also on design, modelling, infor- mation technology, and artificial intelligence. This Special Issue, which after the success of the issue has led to a second edition on similar topics, fits into this context of broad development and offers an updated overview in the field of chemical sensors and new intelligent materials. In fact, these enhanced materials bring together the benefits of many different components promoting in many cases properties and synergistic effects in the field of photonic and plasmonic sensors and biosensors. All this engenders a very effective mode of study and research which supplies substrates and suggestions for industrial needs and applications, ranging from biotechnology and optoelectronics to sensors, while also paying attention to the environmental impact of the processes and technologies described herein. This Special Issue aims to present the advancement of new plasmonic materials, their formulation, functionalization, characterization, and intelligent application in advanced fields, both through point works and reviews.
