TL;DR: In this article, an impedance-based electronic tongue was developed and used to discriminate honey of different botanic origin, based on the small-signal frequency response of the electrical double-layer established between the honey solution and an array of four different sensing units composed by gold, carbon, indium-tin-oxide, and doped silicon.

TL;DR: An electrical method to measure extracellular bioelectrical activity in vitro using the Helmholtz capacitive double-layer established at the electrode surface that is an ideal tool to measure in vitro slow and temporally synchronized events that are often involved in long range intracellular signaling.

TL;DR: In this article, the displacement current method combined with high capacitive polymer-based electrodes is proposed to measure clusters of cells and whole organs, which has great potential in fundamental studies of drug discovery and safety pharmacology.

TL;DR: In this article, the authors demonstrate that the coating of cellulose nanofibers with conducting PEDOT:PSS ink allows the fabrication of a nanostructured surface that establishes a low electrical double-layer resistance with liquid solutions.

TL;DR: The electrodes and the methodology developed here can be used as an ultrasensitive electrophysiological tool to reveal the synchronization dynamics of ultra-slow ionic signalling between non-electrogenic cells.
