“…The QDs had a high quantum yield, low cytotoxicity, were environmentally friendly, and could even be used as a dye to stain live bamboo cells. These exfoliation methods employing BPEs demonstrate simple and cost-effective mechanisms to form desired materials without the use of harsh chemicals.BPEs were used to selectively electrodeposit hydrogels for biological applications by Ino and Shiku and coworkers 146. Ca 2+ -alginate hydrogel was electrodeposited on each anode of an array of BPEs, and the location of deposition was tuned via the position of the driving electrodes, as demonstrated in Figure 7c.…”

The goal of this review is to provide an overview of the advancements made in the field of bipolar electrochemistry over the past 2 years, with an emphasis on analysis. Bipolar electrodes (BPEs) are versatile, and in electroanalysis, they have been used extensively to screen electrocatalysts(1−4) and to sense biomarkers.(5−10) Their ability to modulate local electric fields lends them to the manipulation of cells and to the enrichment and separation of analytes.(11−17) Finally, by virtue of the polar and often graded profile of the interfacial potential across BPEs, they provide a platform for synthesis of Janus particles, useful as sensors and as microswimmers(18−22) and other materials with compositional gradients.(23,24) BPEs are particularly well-suited to analytical challenges that demand multiplexing or amenability to point-of-need (PON) application because even large arrays of BPEs can be controlled with simple equipment yet yield quantitative information about a system. In this review, we discuss recent progress in reactions that transduce current to a visible signal, sensing mechanisms, bipolar electrochemical cell design, integration of bipolar electrochemistry with spectroscopic techniques, BPEs at the nanoscale, and the application of BPEs to electrokinetics and materials preparation. Throughout the discussion, we identify promising trends, innovative directions, and remaining challenges in the field. Disciplines Disciplines Analytical Chemistry Comments Comments

Biofabrication is roughly defined as techniques producing complex 2D and 3D tissues and organs from raw materials such as living cells, matrices, biomaterials, and molecules. It is useful for tissue engineering, regenerative medicine, drug screening, and organs‐on‐a‐chip. Biofabrication could be carried out by microfluidic techniques, optical methods, microfabrication, 3D bioprinting, etc. Meanwhile, electrochemical devices and/or systems have also been reported. In this progress report, the recent advances in applying these devices/systems for biofabrication are summarized. After introducing the concept of biofabrication, biofabrication strategies using electrochemical approaches are summarized. Then, various electrochemical systems such as probes and chip devices are described. Next, the biofabrication of hydrogels for 3D cell culture, electrochemical modification on cell culture surfaces, electrodeposition of conductive materials in hydrogels for cell culture, and biofabrication of cell aggregates using dielectrophoresis is discussed. In addition, electrochemical stimulation methods such as electrotaxis are mentioned as promising techniques for biofabrication. Finally, future research directions in this field and the application prospects are highlighted.

“…For this purpose, electrodeposition is a useful technique for addressable and individual electrode arrays. Since electrodeposition is also applied for hydrogel formation (Ozawa et al, 2013a,b, 2016, 2017; Ino et al, 2018a,d; Taira et al, 2018, 2019; Li et al, 2019), biomaterials including cells are easily patterned only on the target electrodes.…”

Microfluidic devices are widely used for cell analysis, including applications for single-cell analysis, healthcare, environmental monitoring, and organs-on-a-chip that mimic organs in microfluidics. Moreover, to enable high-throughput cell analysis, real-time monitoring, and non-invasive cell assays, electric and electrochemical systems have been incorporated into microfluidic devices. In this mini-review, we summarize recent advances in these systems, with applications from single cells to three-dimensional cultured cells and organs-on-a-chip. First, we summarize microfluidic devices combined with dielectrophoresis, electrophoresis, and electrowetting-on-a-dielectric for cell manipulation. Next, we review electric and electrochemical assays of cells to determine chemical section activity, and oxygen and glucose consumption activity, among other applications. In addition, we discuss recent devices designed for the electric and electrochemical collection of cell components from cells. Finally, we highlight the future directions of research in this field and their application prospects.
