Abstract

This work presents the application of organic semiconductor distributed feedback laser as free-space excitation source in Raman spectroscopy. Surface-enhanced Raman scattering effect is exploited to improve the detection sensitivity. The SERS conditionis achiedved by using substrates consisting of gold-coated polymeric nanopillar arrays. The organic-laser-excited SERS measurements are applied to verify the concentration variation of biomolecule adenosine in aqueous solutions.

Abstract

This book is dedicated to highlighting some relevant advances in the field of thin films and coatings based on two-dimensional crystals and layered nanomaterials. Due to their layered structure, graphene and a variety of new 2D inorganic nanosystems, called “graphene analogues”, have all attracted tremendous interest due to their unprecedented properties/superior performance, and may find applications in many fields from electronics to biotechnology. These two-dimensional systems are ultrathin and, hence, tend to be flexible, also presenting distinctive and nearly intrinsic characteristics, including electronic, magnetic, optical, thermal conductivity, and superconducting properties. Furthermore, the combination of different structures and synergetic effects may open new and unprecedented perspectives, making these ideal advanced materials for multifunctional assembled systems. As far as the field of coatings is concerned, new layered nanostructures may offer unique and multifunctional properties, including gas barrier, lubricant, conductive, magnetic, photoactive, self-cleaning, and/or antimicrobial surfaces. This book contains new findings on the synthesis and perspectives of multifunctional films that are at the forefront of the science and coating technologies.

Abstract

The Special Issue “Synthesis and Modification of Nanostructured Thin Films” highlights the recent progress in thin film synthesis/modification and characterization. New methods are reviewed for the synthesis and/or modification of thin films based on laser, magnetron, chemical, and other techniques. The obtained thin nanostructures are characterized by complex and complementary techniques. We think that most of proposed methods can be directly applied in production, but some others still need further elaboration for long-term prospective applications in lasers, optics, materials, electronics, informatics, telecommunications, biology, medicine, and probably many other domains. The Guest Editor and the MDPI staff are therefore pleased to offer this Special Issue to interested readers, including graduate and PhD students as well as postdoctoral researchers, but also to the entire community interested in the field of nanomaterials. We share the conviction that this can serve as a useful tool for updating the literature, but also to aid in the conception of new production and/or research programs. There is plenty of room for further dedicated R&D advances based on new instruments and materials under development.
