Dear Colleagues,

Spectroscopic techniques are powerful tools for experimental investigation in the infrared (IR) region of organic systems of biophysical interest, such as biopolymers, proteins, cells, organs, and tissues during several processes, as these techniques can highlight, for instance, effects due to changes in temperature, pressure, oxidation, acidification, or exposure to microwaves, UV radiation, etc.

Furthermore, different spectroscopic techniques can couple with different system properties, to explore different spatial scales, to probe different system relaxation times, to highlight specific systems contributions thanks to chemical labeling, to follow the system kinetics, often guaranteeing great accuracy in measurements.

In many cases, the joint employment of different spectroscopic techniques can furnish a deep understanding of complex physical-chemical mechanisms interesting organic systems. For these reasons, spectroscopic techniques are widely employed in biomedicine to detect changes in molecular compositions and structures in organic tissues, for the diagnosis and the monitoring of various diseases.

In this framework, the proposed thematic issue will be a forum for researchers to highlight the new approaches in the applications of spectroscopy for the comprehension of unexplored behavioral mechanisms in organic matter.

Potential topics include but are not limited to the following:

-Study of the secondary structure of proteins in the IR region

-Role of protectant molecules on the structural and dynamical properties of bio-structures

-Modeling biological interactions

-Response of cells and biomolecules to physical-chemical agents

-Behavior of biopolymers under external stresses

-Study of organic tissues and membranes in the IR region

-Diagnosis and monitoring of various diseases

-Study of the response of sick organs to pharmacological or physical treatments

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
