New electrochemical cell for studies of phthalocyanines
Hudská, V. ; Janda, Pavel ; Nesměrák, K.
We have developed a new type of electrochemical cell for electrochemical studies of phthalocyanines. The cell employs a HOPG as a working electrode covered by a thin layer of dichlorobenzene with dissolved phthalocyanine. The layer of dichlorobenzene solution is overlaid by aqueous supporting electrolyte solution where the reference and counter microelectrodes are immersed.

Electrochemical sensor: Mediator Deposition by drop evaporation
Mansfeldová, Věra ; Janda, Pavel ; Tarábková, Hana
Among many different kinds of electrode surface modification procedures, the surface coating by vaporized mediator solution is still used as a simple and effective method for preparation of sensing electrode. Surface of glassy carbon (GC) is often used as a supporting collector, but it requires polishing, rinsing and sonication prior to mediator deposition. In this paper, we present common methods of modification of highly oriented pyrolytic graphite (HOPG) and GC surface, respectively, from the point of surface nanomorphology investigated by atomic force microscopy.

Electrochemical Applications of SPM
Janda, Pavel
The electrochemical scanning probe microscopy (EC SPM) operates in liguids represented by solutions of electrolytes. This technique requires specific instrumentation and approach different from ex situ SPM or UHV tunneling. Some aspects of in-situ application including both atomic force microscopy and tunneling in liquids are discussed.
