Abstract In this work, we report the development of a highly sensitive capacitance chemical sensor based on copper C,C,C,C‐ tetra‐carboxylic phthalocyanine‐acrylate polymer adduct (Cu(II)TCPc‐PAA) for phosphate ions detection. A silicon nitride substrate Al−Cu/Si‐p/SiO 2 /Si 3 N 4 structure was used as transducer. These materials have provided good stability electrochemical measurements. The functionalized silicon‐based transducers with Cu(II)Pc‐PAA membrane were characterized by using...
A novel electrochemical impedimetric sensor based on new copper phthalocyanine derivative-functionalized gold substrates has been developed. The modified transducers have characterized using Fourier transform infrared spectroscopy and contact angle measurements. Under the optimized conditions in terms of polarization frequency range, developed provided a large linear range from 1 × 10−10 to 10−3 M with detection limit 9.48 10−11 M. To minimize sensor's size, microsensor microelectrodes was...
In this paper, we have developed a miniaturized chemical sensor based on new nanostructured Co-phthalocyanine (Co(II)Pc-PAA) derivative functionalized Au microelectrodes for perchlorate ClO <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-</sup> 4 detection.

Abstract We report in this work the development of a novel capacitance electrochemical sensors based on silicon nitride substrate (Si 3 N 4 ) chemically modified with structure Cobalt phthalocyanine, C,C,C,C‐tetracarboxylic acid‐Polyacrylamide (Co(II)Pc‐PAA). This sensitive layer was tested and without magnetic nanoparticles (MNP) for perchlorate ( detection. The developed chemical sensor Si /APTES‐MNP/Co(II)Pc‐PAA has shown better performance when compared to other /Co(II)Pc‐PAA. Contact...
