Special Issue Information

Dear Colleagues,

Luminescence is one of the most interesting physical effects in various fields of science, technology and medicine. Recent advances in related instrumentation and methods, as well as the simplicity of luminescent techniques adapted to a wide variety of applications, has made it very popular in many natural sciences. Luminescent and fluorescent analysis provide some of the most selective and sensitive ways for detecting many molecular compounds, impurities and biological tissues. We are announcing this Special Issue to focus on recent advances in the investigation of luminescence effects and their novel applications.

The scope of this Issue includes bioimaging, phonon-assisted upconversion, luminescent nanothermometry in vivo, analysis of biological tissues, characterization of impurities and color centers in crystals, investigation of intraband and interband transitions, nonlinear effects, quantum dots, and so on.

Dr. Pavel Alexandrovich Danilov
Guest Editor

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.

Confocal scanning Raman and photoluminescence (PL) microspectroscopy is a structure-sensitive optical method that allows the non-invasive analysis of biomarkers in the skin tissue.

Confocal scanning Raman and photoluminescence (PL) microspectroscopy is a structure-sensitive optical method that allows the non-invasive analysis of biomarkers in the skin tissue. We used it to perform in vitro diagnostics of different malignant skin neoplasms at several excitation wavelengths (532, 785 and 1064 nm). Distinct spectral differences were noticed in the Raman spectra of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC), compared with healthy skin. Our analysis of Raman/PL spectra at the different excitation wavelengths enabled us to propose two novel wavelength-independent spectral criteria (intensity ratios for 1302 cm−1 and 1445 cm−1 bands, 1745 cm−1 and 1445 cm−1 bands), related to the different vibrational “fingerprints” of cell membrane lipids as biomarkers, which was confirmed by the multivariate curve resolution (MCR) technique. These criteria allowed us to differentiate healthy skin from BCC and SCC with sensitivity and specificity higher than 95%, demonstrating high clinical importance in the differential diagnostics of skin tumors.
