EDTA. Adapted from Ref. [12] with permission from the American Chemical
Society.
Our group constructed self-powered and intelligent logic ap-
tasensors based on the aptamer-controlled power output of EBFCs
[16]. As shown in Fig. 13.4, this system was composed of a
GOx-/thrombin-binding aptamer-based bioanode and a bilirubin
oxidase-/lysozyme-binding aptamer-based biocathode. The electro-
chemical activity of the modified electrode was switched by the
presence or absence ...
