Special Issue Information
Dear Colleagues,
The advent of the laser, beginning with the first demonstration by Theodore Maiman in 1960, represents a significant milestone in biophotonics and biomedical applications. Lasers offer high precision in imaging and diagnostics such as in optoacoustic or photoacoustic tomography (OAT or PAT), optical coherence tomography (OCT), diffuse optical tomography (DOT), fluorescence optical imaging (FOI), laser Doppler imaging (LDI) and Raman spectroscopy and in minimally invasive therapeutic techniques such as photodynamic therapy (PDT), photothermal therapy (PTT) and low-level laser therapy (LLLT). It is important to note that the application of fluorescence and photoacoustic dual-modality imaging for hypoxia in living cells plays a significant role in tumor hypoxia. In this context, the combination of diagnostics (imaging) and therapeutics, theragnosis, to achieve a more precise and targeted approach to disease management, particularly cancer, is emerging as an important field for the future of lasers in biophotonics and biomedical applications. This area is poised for further innovation driven by emerging technologies including nanotechnology and artificial intelligence (AI): nanotechnology, through the interaction of lasers with nanoparticles, will create more effective and less invasive methods for drug delivery and cancer treatment, while AI will increase the precision of imaging and diagnostics following the acquisition of patient-specific results. By this means, the combination of nanotechnology and AI holds immense potential for scientific and technological advancements in lasers within the context of biophotonics and biomedical applications.

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 250 words) can be sent to the Editorial Office for assessment.
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. Applied Sciences 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 2400 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.
