Special Issue Information

Dear Colleagues,

The emergence of integrated electronics marks the beginning of the integrated devices era. To successfully integrate them, parts should be smaller and smaller, which has led us to the microworld. The technology of creating microelectronics has brought the strong development of photolithography and photoresists. Some researchers have found that this know-how can be used for building integrated optical waveguides and molds for soft lithography to create microchannels as the building blocks of microfluidics. Later, it turned out that integrated optics and microfluidics can be combined. Recently, the interdisciplinary sciences are on the rise. One of them is Biophysics with its really booming field: biosensors. Here are just some examples of their superiority to the traditional techniques: label-free detection (less cost, shorter time, no or minimal demand on central laboratory services), and less sample volume is required.

We have this Special Issue for gathering the recent advances in the blooming field of integrated optical biosensors and their applications. Manuscripts are warmly welcome that report on the newest advances on topics, included but not limited to:

  • Label-free detection;
  • All optical biosensors;
  • Integrated optical sensory devices;
  • Evanescent field-based biosensors (ATR);
  • Surface plasmon resonance sensors;
  • Bragg Grating Fiber sensors (FBG);
  • Integrated optical microcavity sensors.

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. Sensors 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 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.

This review introduces a micro-integrated device of microfluidics and fiber-optic sensors for on-site detection, which can detect certain or several specific components or their amounts in different samples within a relatively short time. Fiber-optics with micron core diameters can be easily coated and functionalized, thus allowing sensors to be integrated with microfluidics to separate, enrich, and measure samples in a micro-device. Compared to traditional laboratory equipment, this integrated device exhibits natural advantages in size, speed, cost, portability, and operability, making it more suitable for on-site detection. In this review, the various optical detection methods used in this integrated device are introduced, including Raman, ultraviolet–visible, fluorescence, and surface plasmon resonance detections. It also provides a detailed overview of the on-site detection applications of this integrated device for biological analysis, food safety, and environmental monitoring. Lastly, this review addresses the prospects for the future development of microfluidics integrated with fiber-optic sensors. Full article
