Dear Colleagues,

Optofluidic devices are of high scientific and industrial interest in chemistry, biology, material science, pharmacy, or medicine. In recent years, they have experienced a strong development because of impressive achievements of the synergistic combination of photonics and micro/nanofluidics. The key elements of these devices are their transducers that transform the slightest changes in a media in a quantifiable optical signal.

Thus, sensing platforms incorporating these optofluidic transducers show unprecedented sensitivities in extremely small analyte volumes, and allow real time analysis within a lab-on-a-chip approach. Many of them are based on the interaction of fluids with evanescent waves induced at metal/dielectric interfaces, at the surface of truncated photonic crystals, at integrated Mach-Zehnder interferometers, on the use of plasmonic filters based on the extraordinary optical transmission, or on the implementation of microcavities to induce optical resonances in fluid media.

In this context, a large variety of optofluidic transducers have emerged, covering topics such as bio-sensing, water analysis/environmental monitoring, liquid agrofood safety, catalytic reactions, microparticle sorting, medical diagnostic technologies, drug discovery, or micro-imaging. Moreover, integration of these devices in larger electro-optic platforms represents a highly valuable improvement towards advanced applications, such as those based on surface plasmon resonances, already in the market.

In this Special Issue, we invite the scientific community working in this rapidly evolving field to publish recent research and/or review papers on these optofluidic transducers.

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. Micromachines 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 2600 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.
