Special Issue Information

Dear Colleagues,

In recent years, an increasing number of optical techniques have been applied in the field of biomedicine, playing a significant role in both diagnosis and treatment. Traditional medical diagnosis and treatment with drugs are facing many disadvantages such as damage and weak timeliness. Therefore, non-destructive detection technology and drug-free treatment auxiliary schemes will be one of the main development trends in the future.

Spectroscopy methods like Raman spectroscopy, laser-induced breakdown spectroscopy (LIBS), and fluorescence bring the chemical composition directly into the diagnosis. Microscopy, super-resolution techniques, hyperspectral imaging, and polarized optics provide more detailed space and spectral information. Optical technology has opened up new perspectives for biomedical applications, offering a fresh approach that is gradually transitioning from the laboratory to clinical practice, leading to a transformation in the field of biomedicine.

Given your expertise and significant contributions to the field, we are particularly interested in receiving a manuscript from you on your latest research findings or a review article highlighting the recent advancements in the application of optical techniques in biomedical research. We believe that your work would greatly benefit our readership and make a valuable addition to the scientific literature.

In this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

  • Optics and spectroscopy in biomedical analysis;
  • Optical diagnosis (cancer, other diseases, clinical samples, etc.);
  • Multimodal imaging;
  • Molecular imaging and therapies;
  • Optical biophysics;
  • Nanophotonic biosensing;
  • Pharmaceutical analysis;
  • Non-destructive detection.

I/We look forward to receiving your contributions.

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. Photonics is an international peer-reviewed open access monthly 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.

Normal vision is a precious gift to mankind. Any vision defect or degradation is actually an intimidating problem for individuals and societies. Therefore, researchers are continually working to find effective solutions for vision disorders. In some retinal diseases such as Age-related Macular Degeneration (AMD), visual aids are required to improve vision ability and/or stop the progress of the disease. Recently, augmented vision techniques have been used to provide aid to people suffering from retinal impairment. However, in such techniques, the images of real scenes are electronically deformed to compensate for vision impairment. Therefore, the natural scene is displayed as an electronic image on glasses. Intuitively, it is annoying to the patient to see electronic rather than natural scenes. Moreover, these visual aids are bulky and produce electric fields that might be harmful with continuous use. In this work, a novel optical solution to provide a visual aid to patients with central vision loss has been proposed. The proposed optical solution deforms the wavefront of the scene to entirely fall on the healthy parts of the retina. This, in turn, conveys all scene information to the brain to be perceived by the patient. As it provides optical processing, the proposed solution overcomes all drawbacks of the electronic solutions. To prove the validity of the proposed solution, three lenses were designed, fabricated, and tested to visualize simple shapes, reading, and obtaining aid during walking and driving. Obtaining the expected results from these tests, they were tried by three volunteers to clinically prove the validity and feasibility of the proposed optical aid. The feedback from the three patients was promising since all of them could recognize some of the details they used to miss with at least one of the lenses. Full article
