Special Issue Information
Dear Colleagues,
Optical fluorescence imaging significantly reduces patient exposure to harmful radiation by using nonionizing radiation. Fluorescence light generates images by exciting electrons without causing the damage that can occur with ionizing radiation used in radiation-based medical imaging techniques. Because it is much safer for patients, and significantly faster, optical imaging can be used for lengthy and repeated procedures over time to monitor the progression of disease or the results of treatment. Optical imaging has been one of the primary imaging techniques that have been employed in various disciplines due to their high sensitivity and real-time data feedback. Traditional optical imaging modalities utilize the visible (400-650 nm) and the near-infrared region (NIR I; 650-900 nm); however, deep tissue imaging has recently been carried out in the NIR-II window (1000-1300 nm) using shortwarve infrared (SWIR) contrast agents. NIR-I/II imaging has several special features for high-resolution imaging of biological tissue including deep tissue penetration, low autofluorescence, and low light abosrption and scattering in the neighboring tissues, which together make it ideal to help guide the surgeon in real-time. The benefit of using optical imaging in the clinical setting can be attributed to its molecular fluorescence as an exogenous contrast agent. In particular, the use of multispectral, targeted NIR fluorophores enables real-time delineation of diseased tissue while preserving vital tissues. In this Special Issue, we report the recent advances in (1) the development of NIR I and NIR II contrast agents, (2) the measurements of their optophysical properties, sensitivity, targetability, and stability, (3) their biomedical, bioanalytical, and bioimaging applications, (4) and diagnosis and treatment of human diseases.

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.
