Nickel tetrasulfonated phthalocyanine based platinum microelectrode array for nitric oxide oxidation

Electropolymerization of Phthalocyanines

“…There are several publications [67][68][69][70][71][72][73][74], as well as our own investigations, where voluntarily the field is referred to as Pc electropolymerization. However, the authors working in this field use the term electropolymerization [67][68][69][70][71][72][73][74], and hence its usage in the present chapter.…”

“…However, the authors working in this field use the term electropolymerization [67][68][69][70][71][72][73][74], and hence its usage in the present chapter. NiTSPc is the most popular precursor for a very peculiar anodic modification of electrode surface.…”

Cell-compatible array of three-dimensional tip electrodes for the detection of nitric oxide release

“…The sensitivity of the electrode array towards nitric oxide was improved by modification with nickel tetrasulfonate phthalocyanine tetrasodium salt, a well established electrocatalyst for the oxidation of nitric oxide (Pereira-Rodrigues et al, 2002;Pailleret et al, 2003).…”

“…The electrodes in the array were selectively modified with a well established nitric oxide sensing chemistry (Pereira-Rodrigues et al, 2002;Pailleret et al, 2003) based on the electrochemically induced deposition of nickel tetrasulfonate phthalocyanine tetrasodium salt onto the individual electrode surfaces. The related cyclic voltammetry recorded during the electrochemical deposition of the catalyst layer is shown in Fig.…”

“…4a. The formation of a film of this phthalocyanine on the electrode surface is indicated by the appearance and increase in the peak currents of the anodic and cathodic signals at 420 and 580 mV versus Ag|AgCl (Pereira- Rodrigues et al, 2002;Pailleret et al, 2003). The molecular structure of nickel tetrasulfonate phthalocyanine tetrasodium salt is shown as an inset in Fig.…”
