“…The effect was initially ascribed to the increased surface area of the roughened electrode, but in 1977 Albrecht and Creighton [6], and Jeanmaire and van Duyne [7], independently confirmed that the intense Raman signals actually reflected a true surface enhancement of the Raman scattering efficiency, as compared with the normal scattering crosssection of bulk pyridine. Currently, such enhancement can be directly observed in metal nanoparticles displaying plasmonic resonance, such as those of copper, silver and gold, and for this reason SERS has become a very important subject in nanotechnology and in medicine [2,[8][9][10][11][12][13][14][15][16] The SERS effect can also be observed in some semiconductors and graphene nanostructures involving surface plasmon resonance [17]; however, systematic studies are yet missing in the literature.…”

“…Solvent anchoring reduces the contact area of a lowviscosity liquid and helps concentrate target mole cules within a localized region to enhance the SERS signal, as shown in Figure 8f,g. The combination of a portable Raman spectrometer with a highly sensitive and uniform SERS substrate is highly expected to be commercialized for on-site chemical analysis in environmental monitoring, [114] food safety, [115][116][117][118] forensic science, [119,120] and point-of-care medical diagnostics.

In this paper, the authors review the optical principles underlying the fabrication of 3D periodic nanostructures prepared using holographic lithography (HL) as well as their applications toward chemical sensors and energy storage devices using 3D functional nanomaterials. HL is potentially useful for the simple and rapid fabrication of defect‐free large‐area periodic nanostructures with various structural geometries. The use of optical elements, such as well‐designed prisms and diffraction gratings, improves the reproducibility of the manufacturing process by simplifying complicated optical setups. 3D functional nanostructures, including semiconductor and metallic nanomaterials, are useful in highly sensitive photonic crystals and plasmonic sensors, and high‐performance 3D electrodes for use in energy production and storage devices.

“…Its potential allows studying natural fibres based on cellulose [5], carbon-based structures [6], as well as biological systems, artworks or food. Raman spectroscopy offers benefits that are important for the process control in terms of quality control in production, in use [7], but also for forensic identification [4]. Because of its many advantages, Raman spectroscopy was chosen for the study of textile fibres and creation spectral database.…”

Raman spectroscopy as an effective tool for material identification offers benefits that are important for the process control of the fibres in terms of quality control in production, in use, but also in the field of fibre analysis for forensic identification. In particular, it is specific information on chemical composition and structure of material; rapidity of measurement, non-destructiveness, independence on chemicals, portability, possibility of automation of measurements and ability to detect structural changes. In the study, samples of natural and synthetic polymer fibres were measured and analysed. For the evaluation of large spectral data sets multivariate analysis techniques were applied to find the patterns within the data. The spectral database was created on the basis of the acquired Raman spectra of textile fibres and was successfully tested on other samples. The results show a great potential of the used method for the fibre identification.
