Novel Sensitive Impedimetric Microsensor for Phosphate Detection Based on a Novel Copper Phthalocyanine Derivative

A novel electrochemical impedimetric sensor based on new copper phthalocyanine derivative-functionalized gold substrates has been developed. The modified transducers have been characterized using Fourier transform infrared spectroscopy and contact angle measurements. Under the optimized conditions in terms of polarization and frequency range, the developed sensor provided a large linear range from 1 × 10−10 to 1 × 10−3 M with a detection limit...
