TL;DR: The characteristics of three different carbon electrodes, glassy carbon (GC), oxygen-terminated polycrystalline boron-doped diamond (pBDD) and "pristine" carbon nanotube networks (CNTN) as voltammetric sensors for detection of the serotonin have been investigated.

TL;DR: A multiprobe platform for the investigation of single-walled carbon nanotubes is introduced that allows the electrochemical response of an individual SWNT to be mapped at high spatial resolution and correlated directly with the intrinsic electronic and structural properties.

TL;DR: It is highlighted how the film density, level of sp(2)/sp(3) rehybridization and the extent of multilayer formation can be controlled, paving the way for the use of localized electrochemistry as a route to controlled diazonium modification.

TL;DR: The electron transfer (ET) kinetics of three redox couples in aqueous solution on different grades of highly oriented pyrolytic graphite (HOPG) have been investigated in a droplet-cell setup, showing that the ET kinetics for all of the redox species studied herein is fast on all grades of HOPG and lower limits for ET rate constants are deduced.

TL;DR: The fabrication and use of a multifunctional electrochemical probe incorporating two independent carbon working electrodes and two electrolyte-filled barrels, equipped with quasi-reference counter electrodes (QRCEs), in the end of a tapered micrometer-scale pipet is described, demonstrating the utility of the technique.
