Electrochemical activity and electrocatalytic property of cobalt phthalocyanine nanoparticles-based immunosensor for sensitive detection of procalcitonin

- NanoCoPC decorated MWCNTs was synthesized.
- Detection signal is based on the redox property nanoCoPc without introduction other redox mediator.
- A pseudobienzyme amplified strategy was based on electrocatalytic of nanoCoPc and catalytic activity of choline oxidase.
