Special Issue Information
Dear Colleagues,
Lab-on-a-chip (LOC) is a technology that allows researchers to shrink a bio/chemical/medical labs onto a chip the size of a small coin. Due to the miniaturization and automation of those bio/chemical/medical procedures, LOC has demonstrated its ultrahigh sensitivity, short diagnostic time, cost efficiency, and so on, which have revolutionized traditional bio/chemical/medical fields.
LOC technology is still far from commercialization. There are many challenges, and we will try to tackle the challenges related to sensors in this Special Issue, “Sensors and Lab-on-a-Chip”. For practical applications, LOC systems need suitable sensors, which we can categorize into three approaches: (1) ideally, the sensors should be disposable along with LOC. For example, CMOS, electrochemical, FET, RF, mechanical, and optical sensors have been integrated with LOC devices for on-chip sensing. The challenge here is, not only to enhance the quality of the on-chip sensors, but also to fabricate the LOC devices cost-effectively. (2) the sensors can do the sensing without being affected by test solutions, thus they can be reused and only the microfluidic parts are disposable. For this approach, user-friendly, contamination-free, modular interfacing between the microfluidic devices and the sensing systems need to be highlighted, along with compact designs for the sensing systems. Recent examples include a lens-free holographic microscope installed on an existing smart phone camera. 3) Another methodology is to utilize mobile micro/nano particles/cells as sensing units in microfluidic devices that can be excited and scanned using external optical or magnetic systems, such as micro SERS (surface enhanced Raman scattering), micro SPR (surface plasmon resonance) and giant magnetoresistance sensors (GMR).
We invite investigators to submit original research articles and reviews to this Special Issue. Potential topics include, but are not limited to, recent developments in the following areas: Fabrication and application of LOC; sensors for LOC systems; CMOS sensors; capacitive sensors; electrochemical sensors; FET sensors; RF sensors; on-chip mechanical sensors (e.g., cantilever, QCM, SAW); on-chip optical sensors; lens-free smartphone microscopes; micro SERS; micro SPR; GMR; cell-based sensors; and nanobio sensors. Authors are invited to contact the Guest Editors prior to submission if they are uncertain whether their work falls within the general scope of this Special Issue.

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.
