Fostered by the remarkable progress in the fabrication of nanoparticles and nanostructures, in the last years Surface-Enhanced Raman scattering (SERS) has reached an impressive diffusion in many fields of chemistry and analytical sciences. Several exciting results have been recently reported in SERS-based ultrasensitive detection and molecular imaging. However, more than forty years after its discovery, conventional SERS is still struggling to make its way as a reliable analytical method. The remarkable enhancement of the local electromagnetic field achieved by plasmonic nanostructures is indeed a double-edged sword, as in pushing the sensitivity to the ultimate level, it strongly limits accuracy and reproducibility of the Raman data. In this context, non-plasmonic or hybrid plasmon/dielectric systems are emerging as a promising alternative/complement to conventional SERS. Core/shell systems like T-rex or SHiNERS are only a few examples of these novel SERS-active platforms. In parallel, new theoretical models, based on quantum optomechanical approaches have been recently proposed and developed for describing and predicting plasmonic, non-plasmonic and hybrid (e.g. photo-induced enhanced Raman scattering, PIERS) SERS, also including opto-thermal effects. Moreover, the next-generation of SERS-active materials is facing new challenges in terms of detection strategies, integration with complementary methods and stimuli responsiveness. This Research Topic collects the most recent advances in SERS and related effects, from the viewpoint of theory/models, materials and detection strategies, providing an up-to-date forum for setting the basis for future research in this vibrant field.

In this work we studied the synthesis, dispersion and wet deposition of molybdenum-tungsten hybrid oxide as novel plasmonic electrochromic materials. We successfully synthesized these hybrid materials using a one step solvothermal route. The recovered powders were characterized in terms of their morphology, crystallinity, optic properties, and behavior under annealing conditions. Then, the powders were dispersed in usual low toxic solvents to be used as "electrochromic inks" for the ensuing deposition. The stability of the dispersions was evaluated both qualitativelly and quantitatively, with and without addition of stabilizing agents. The best results were obtained using either a dispersing agent (PEG 140k in ethanol and PEI in water) or in the case of heavily loaded suspensions (150 mg/mL), taking advantage of the interparticle steric hindrace. 10 mg/mL dispersions with PEG in ethanol and 150 mg/mL surfactant-free dispersion in ethanol were used as active "inks" for spin coating and bar casting respectively. We managed to produce active films using both techniques, however, the superior quality of the deposited film using bar casting led to improved electrochromic properties

Plasmonics is a rapidly developing field that combines fundamental research and applications ranging from areas such as physics to engineering, chemistry, biology, medicine, food sciences, and the environmental sciences. Plasmonics appeared in the 1950s with the discovery of surface plasmon polaritons. Plasmonics then went through a novel propulsion in the mid-1970s, when surface-enhanced Raman scattering was discovered. Nevertheless, it is in this last decade that a very significant explosion of plasmonics and its applications has occurred. Thus, this book provides a snapshot of the current advances in these various areas of plasmonics and its applications, such as engineering, sensing, surface-enhanced fluorescence, catalysis, and photovoltaic devices.

The rise of photonics technologies has driven an extremely fast evolution in biosensing applications. Such rapid progress has created a gap of understanding and insight capability in the general public about advanced sensing systems that have been made progressively available by these new technologies. Thus, there is currently a clear need for moving the meaning of some keywords, such as plasmonic, into the daily vocabulary of a general audience with a reasonable degree of education. The selection of the scientific works reported in this book is carefully balanced between reviews and research papers and has the purpose of presenting a set of applications and case studies sufficiently broad enough to enlighten the reader attention toward the great potential of plasmonic biosensing and the great impact that can be expected in the near future for supporting disease screening and stratification.
