Special Issue Information

Dear Colleagues,

Biodetection and sensing are increasingly pertinent subjects in today’s climate—both for public health as well as the health of our environment—and the widely known benefits of using microfluidics could facilitate better, faster, and safer detection and monitoring of potential biothreats and chemicals around us.

Microfluidics is a multidisciplinary technology that interconnects several different areas of science, including chemistry, engineering, physics, and biology, and enables an increasing number of applications. Advances in liquid handling using micro- and nano-sized volumes allow for the automation of cumbersome and time-consuming laboratory unit operations (LUOs) such as purification, extraction, washing and separation, aliquoting, and incubation of samples prior to detection. Key advantages associated with microfluidics-based platforms with integrated detection and sensing include (i) the reduced consumption of reagents, (ii) the ability for rapid biodetection/sensing because of tiny volumes, (iii) the process intensification due to large surface-to-volume ratio, (iv) the high level of integration enabling portability and multi-functionality for point-of-need testing and monitoring.

There have been significant advances in both biosensor technology and in microfluidics, but a successful integration between these two somewhat disparate fields is key. Therefore, this Special Issue seeks to showcase research papers, and review articles that focus on the intersection of microfluidics and biodetection/sensing technologies, with particular interest being paid to detection and sensing technologies that are favorable for integration into microfluidics devices. Novel contributions that demonstrate clever approaches in any of the above listed research areas with integration in sight are also welcome.

Three-dimensional (3D) cell cultures and organs-on-a-chip have been developed to construct microenvironments that resemble the environment within the human body and to provide a platform that enables clear observation and accurate assessments of cell behavior. However, direct observation of transendothelial electrical resistance (TEER) has been challenging. To improve the efficiency in monitoring the cell development in organs-on-a-chip, in this study, we designed and integrated commercially available TEER measurement electrodes into an in vitro blood-brain barrier (BBB)-on-chip system to quantify TEER variation. Moreover, a flowing culture medium was added to the monolayered cells to simulate the promotion of continuous shear stress on cerebrovascular cells. Compared with static 3D cell culture, the proposed BBB-on-chip integrated with electrodes could measure TEER in a real-time manner over a long period. It also allowed cell growth angle measurement, providing instant reports of cell growth information online. Overall, the results demonstrated that the developed system can aid in the quantification of the continuous cell-pattern variations for future studies in drug testing. Full article
