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.

Inertial microfluidics has become a popular topic in microfluidics research for its good performance in particle manipulation and its advantages of simple structure, high throughput, and freedom from an external field. Compared with traditional microfluidic devices, the flow field in inertial microfluidics is between Stokes state and turbulence, whereas the flow is still regarded as laminar. However, many mechanical effects induced by the inertial effect are difficult to observe in traditional microfluidics, making particle motion analysis in inertial microfluidics more complicated. In recent years, the inertial migration effect in straight and curved channels has been explored theoretically and experimentally to realize on-chip manipulation with extensive applications from the ordinary manipulation of particles to biochemical analysis. In this review, the latest theoretical achievements and force analyses of inertial microfluidics and its development process are introduced, and its applications in circulating tumor cells, exosomes, DNA, and other biological particles are summarized. Finally, the future development of inertial microfluidics is discussed. Owing to its special advantages in particle manipulation, inertial microfluidics will play a more important role in integrated biochips and biomolecule analysis. Full article
