Other types of planar NO microsensors include Pt microelectrodes chemically modified by electrodeposition of metaUoporphyrin-like nickel(II) complexes. For example, tetrasul-fonated phthalocyanine tetrasodium (NiTSPc) was electrodeposited on the bare electrode surface by repetitive cychc voltammetry (21). Alternatively, electrode functionalization using nickel(4-iV-tetramethyl)pyridyl porphyrin (NiTmPyP) as an electrocatalyst was also carried out by applying multiple pulses in differential pulse amperometry (22). In this case, the electrocatalyst was entrapped in a NO selective polymer network of a negatively charged acrylic acid resin that prevented access by anionic interfering species.
