Special Issue Information

Dear Colleagues,

In recent years, the enabling role of optics and photonics in the field of biosensing has developed rapidly. Optical and photonic biosensors, which are mainly intended for health applications, environmental monitoring, and food/water quality control, are advanced enough to enter the market, and the amount of research in this field is increasing.

The Special Issue will provide a forum for the last research activities on photonic biosensors. Theoretical and experimental papers are solicited in, though they are not limited to, the following areas:

  • Micro-photonic chip-based biosensors;
  • Fiber-optic biosensors;
  • Lab-on-fiber devices;
  • Photonic biosensors based on metasurfaces and photonic crystals;
  • Optofluidic biosensors;
  • Plasmonic biosensors based on surface plasmon resonance, localized surface plasmon resonance, and surface-enhanced Raman scattering;
  • Emerging application of photonics in the field of biosensing;
  • New materials and physical concepts intended for photonic biosensors;
  • Spectroscopy for biosensing;
  • High-resolution imaging;
  • Super-resolution microscopy;
  • Nano-plasmonic biosensor for in vivo and ex vivo analysis;
  • Three-dimensional printing for optical biosensor fabrication;
  • Novel materials for implantable optical devices.

Review papers focused on specific aspects of the field of photonic biosensors are encouraged, especially if they provide a comprehensive and critical analysis, taking into account the applications needs and market prospects.

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. Biosensors 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 2700 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.

Surface-enhanced Raman spectroscopy (SERS) represents a transformative tool in medical diagnostics, particularly for the early detection of key biomarkers such as small extracellular vesicles (sEVs). Its unparalleled sensitivity and compatibility with intricate biological samples make it an ideal candidate for revolutionizing noninvasive diagnostic methods. However, a significant challenge that mars its efficacy is the throughput limitation, primarily anchored in the prerequisite of hotspot and sEV colocalization within a minuscule range. This paper delves deep into this issue, introducing a never-attempted-before approach which harnesses the principles of crystallization—nucleation and growth. By synergistically coupling lasers with plasmonic resonances, we navigate the challenges associated with the analyte droplet drying method and the notorious coffee ring effect. Our method, rooted in a profound understanding of crystallization’s materials science, exhibits the potential to significantly increase the areal density of accessible plasmonic hotspots and efficiently guide exosomes to defined regions. In doing so, we not only overcome the throughput challenge but also promise a paradigm shift in the arena of minimally invasive biosensing, ushering in advanced diagnostic capabilities for life-threatening diseases.

Polydopamine (PDA), the synthetic counterpart of melanin, is a widely investigated bio-inspired material for its chemical and photophysical properties, and in the last few years, bio-application of PDA and PDA-based materials have had a dramatic increase. In this review, we described PDA application in optical biosensing, exploring its multiple roles as a nanomaterial. In optical sensing, PDA can not only be used for its intrinsic fluorescent and photoacoustic properties as a probe: in some cases, a sample optical signal can be derived by melanin generation in situ or it can be enhanced in another material thanks to PDA modification. The various possibilities of PDA use coupled with its biocompatibility will indeed widen even more its application in optical bioimaging. Full article
