Title: Cobalt phthalocyanines as sensors for determination of thiol groups Annotation: The possibility of employment of cobalt phthalocyanine as a material for the modification of HOPG electrode for construction of a sensor for quantification of thiol groups was studied. Thiol groups are occurring in various biologically active substances (sulfur amino acids). The electrochemical behavior of cobalt tetraneopentoxy-phthalocyanine (CoTNPc) in the water/organic phase system was studied, and individual peaks of cyclic voltammogram of the compound were identified. The electrodeposition of CoTNPc on HOPG electrode was found as a suitable method for construction of the sensor for quantification of thiol groups. The reproducibility of fabrication of the sensor and its time-stability was studied. The calibration dependencies for model analytes (cysteine hydrochloride and homocysteine) were measured. Key words: thiols, phthalocyanines, amperometric sensor, cyclic voltammetry
