“…While ECL has several distinct advantages, its requirement for specialized reagents, sensitive optical equipment, and its restriction to the sensing of primarily reduction reactions are important limitations that have motivated the development of a wide range of versatile reporting mechanisms. Among the most prominent are fluorogenic reactions, ,, electrochromic reactions (such as Prussian blue (PB) − or methyl viologen , ), and the electrodissolution of thin metal films. ,,, Table summarizes a selection of both established and recently developed reporting reactions and delineates the relative advantages of each.…”

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

“…Based on the electrochromism of Prussian Blue films, a resettable and reprogrammable enzymatic keypad lock system was presented for the direct detection of ascorbic acid and glucose by the naked eye. (96) Fluorescence based reporting reactions were also combined with BPE and enzymes. The oxidation of dihydroresorufin into resorufin, a highly fluorescent dye, was successfully applied for the detection of glucose and H2O2 using enzyme modified electrodes at the reporting site.…”

This contribution reviews a selection of the most recent studies on the use of bipolar electrochemistry in the framework of analytical chemistry. Despite the fact that the concept is not new, with several important studies dating back to the middle of the last century, completely novel and very original approaches have emerged over the last decade. This current revival illustrates that scientists still (re)discover some exciting virtues of this approach, which are useful in many different areas, especially for tackling analytical challenges in an unconventional way. In several cases, this “wireless” electrochemistry strategy enables carrying out measurements that are simply not possible with classic electrochemical approaches. This review will hopefully stimulate new ideas and trigger scientists to integrate some aspects of bipolar electrochemistry in their work in order to drive the topic into yet unexplored and eventually completely unexpected directions. Expected final online publication date for the Annual Review of Analytical Chemistry, Volume 14 is June 2021. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

“…This step modified the structurebased color of the metamaterial. Electrochromism was also successfully exploited to sense various analytes in a bipolar configuration (181,182,(280)(281)(282)(283)(284)(285)(286). Wang and co-workers introduced a renewable display platform based on bipolar electrochromic readout for high-throughput screening applications (284).…”

Bipolar electrochemistry is a technique that involves two opposite chemical processes, namely an oxidation and a reduction, occurring simultaneously on the surface of a conducting object, usually without connection to a power supply. The basic phenomenon has already been described and used for many decades but regained a lot of interest in recent years, thanks to several attractive features for developing new applications in various areas ranging from materials science and analytical chemistry to catalysis and even life science. Consequently, bipolar electrochemistry has experienced a substantial growth in the number of users and publications. This is mostly due to several advantages over classic electrochemistry, such as the absence of an ohmic contact, the generation of a directional gradient of electroactivity on the object, and the possibility to address simultaneously thousands of objects, which opens the door for high throughput screening of (electro)chemical properties. Also, some features of this "wireless" electrochemistry allow performing experiments that cannot be achieved with a classic electrochemical setup. Last but not least, only rather low-cost equipment is needed. The objective of the present contribution is to introduce first some fundamental aspects of bipolar electrochemistry, and then to illustrate its different developments, highlighting not only the historic landmark achievements, but also the most recent findings, especially in the context of micro-and nanoscience. The chapter will illustrate the singularities and advantages of this straightforward approach and hopefully convince the reader of the power of this interesting electrochemical concept.
