“…It was found that experimental spectra from biomolecules correlate reasonably well with computational predictions, that the spectra from different cells are sufficiently different, and that cells can be identified based on their spectral signature. Computational modeling results confirmed that the observed spectroscopic features from cells can be ascribed to fundamental physical interaction mechanisms between THz radiation and biological macro-molecules inside the cell [26][27][28]. In particular, the results show that spectroscopic signatures of microorganisms originate from combinations of modes or group of low frequency vibrational modes at close frequencies (vibrational bands) within the molecular components inside the cells [26].…”

“…Besides, to provide the needed information the spectral resolution of spectroscopic instruments has to be less than the spectral width of features to be measured. Although multiple resonance absorption lines in sub-THz region have been reported in measurements with appropriate spectral resolution, for example [8][9][10][11][12][13], successful application of THz spectroscopy for DNA, RNA and protein characterization requires deep understanding of relaxation processes of atomic dynamics (displacements) within a macromolecule. The dissipation time is one of the fundamental problems related to THz vibrational modes in biological molecules.…”

“…Over the last 3 years, this new, sub-THz spectroscopic instrument was used to measure transmission/absorption spectra from biomolecules and cells demonstrating very intense and narrow spectral features with widths between 0.05 cm -1 and 0.15 cm -1 [20,[27][28][29] that reflect low frequency molecular motions. It was found that experimental spectra from biomolecules correlate reasonably well with computational predictions, that the spectra from different cells are sufficiently different, and that cells can be identified based on their spectral signature.…”

Spectral Analysis Review is an international journal dedicated to the latest advancement of all areas of spectroscopy. The primary goal of this journal is to provide a plat-form for scientists and academicians all over the world to provide, share and discuss various new issues and developments in different aspects of spectroscopy. It aims to determine the state-of-the art and advances progress in the field of spectroscopy and get through its developments.I have reviewed the literature regarding spectroscopy. Most of the scientific reports recommend that more spectroscopic investigation should be on modeling and simulation, in addition to the spectroscopic properties of nanomaterials [1][2][3][4]. I would like to stress that modeling and simulation related work would not only promote understanding the spectroscopic properties of materials and nanomaterials but also enhance more bringing their applications to life. In the same way, coupling modeling and computational studies with nanotechnology will help to develop the designing of nanomaterials with required spectroscopic properties. More interesting is the research related to real applications or models. Examples are; spectroscopic characterization of vibrational modes in artificially designed DNA [5], nonlinear optical spectroscopy for biomolecular structure at solid-liquid interfaces [6], modeling and spectroscopic evidence of antimony adsorption on iron-oxide-rich red earth soils [7], single-molecule studies of intrinsically disordered proteins [8], spectroscopic study of model amyloid β-peptide oligomers [9] and other directions [10][11][12][13].The editors will always be pleased to receive the following types of inputs or submissions, among others: 1) Research Highlight articles-generally substantial, current review articles that can be expected to be of interest to the spectroscopy community, 2) Research Notes-research announcements, 3) News and Views, and "In Brief" items-announcements and news items, and 4) Meeting announcements, meeting reports and book reviews.On the side of education, as a community, we need to assess our strategy for teaching and maintaining interest in the field of spectroscopy. Spectroscopic research is rapidly changing and evolving, and it presents many opportunities. Many education innovators may embrace the advancements and examine the rebooting of the academy through a collection of essays. These may explore how to implement new approaches to teaching and research with the use of digital tools; ensure access to lessons and lectures; and take the class time to the high level of interactivity.Happy Reading.

“…Substrates can be roughened metal films to highly ordered plasmonic nanostructure assemblies with nanometer-scale control over size, shape, and distance have been fabricated using various lithographic and nonlithographic methods and tested for the trace-level detection of various analytes. Examples include spectroscopic characterization of vibrational modes in artificially designed DNA and nonlinear optical spectroscopy for biomolecular structure at solid-liquid interfaces [19]- [21]. Substrates of gold nanomaterials were reported to enhance the detection limits of human serum albumin through SERS [22].…”

The detection of trace levels of chemical, biological and other analytes has many important applications, including industry, forensics and environmental monitoring. Detection Journal is an international journal dedicated to the latest advancement of all areas that are related to detection. Nanotechnology based detection techniques may provide major advantages of low detection limits and rapid testing. This may allow scientists to know early about the case and provide the potential of stopping the problem at earlier stages.
