TLDR
In this paper, the structure of polypyrrole was laterally deposited with the scanning electrochemical microscope onto conducting substrates from aqueous solutions with non-restricted diffusion properties.Abstract:
Structures of polypyrrole that were laterally deposited with the scanning electrochemical microscope onto conducting substrates from aqueous solutions with non-restricted diffusion properties have been reported for the first time. The polymer lines obtained are predominantly determined by the size of the microelectrode.read more

TL;DR: SECM has been adapted to investigate charge transport across liquid/liquid interfaces and to probe charge transport in thin films and membranes and has been combined with several other nonelectrochemical techniques, such as atomic force microscopy, to enhance and complement the information available from SECM alone.

Scanning Electrochemical Microscopy for Direct Imaging of Reaction Rates
TL;DR: Scanning electrochemical microscopy offers the possibility of directly imaging heterogeneous reaction rates and locally modifying substrates by electrochemically generated reagents, and processes can be studied that occur at liquid surfaces and liquid-liquid interfaces.

Scanning electrochemical microscopy. Introduction and principles
TL;DR: In this paper, different modes of operation for the SECM are discussed, including collectlon modes, where products electrogenerated at the substrate are detected at the tip (held at constant potentlal or operated In the cyclic voltammetrlc mode), and feedback modes where the effect of substrate on the tlp current is monltored.

Chemical derivatization of an array of three gold microelectrodes with polypyrrole: Fabrication of a molecule-based transistor
TL;DR: In this paper, a chemically derivatized microelectrode array that can function as a transistor when immersed in an electrolyte solution is described, and the key finding is that a small signal (charge) needed to turn on the device can be amplified.
