Abstract

<abstract abstract-type="graphical" xml:lang="en"> <title> <x xml:space="preserve">Abstract</x> </title> <p>Generator–collector microwell arrays show excellent performance for selective and sensitive detection of an analyte of interest in the presence of interferents, with redox waves occurring before that of the analyte. Due to the specific geometry of the array and the adequate control of each electrode potential, the analyte signal is increased by redox cycling, while that of the interferent is drastically reduced. The theory and simulations presented on <ext-link ext-link-type="doi" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink">p. 1887</ext-link> by I. Svir, C. Amatore et al. not only allow proper modeling of the experimental results, but also open up new operating possibilities.<boxed-text content-type="graphic" position="anchor" orientation="portrait"><graphic position="anchor" mimetype="image" xlink:href="ark:/27927/pgg2248wpn2" orientation="portrait" xlink:type="simple" xmlns:xlink="http://www.w3.org/1999/xlink" /></boxed-text></p> </abstract>
