Simple, fast and environmentally friendly method to determine ciprofloxacin in wastewater samples based on an impedimetric immunosensor.

ABSTRACT: In this study an impedimetric immunosensor was developed in order to determine ciprofloxacin (CIP) in wastewater samples, an emergent contaminant widely found in wastewater. To achieve this, an anti-ciprofloxacin antibody was immobilized on the surface of a printed carbon electrode. Then, the developed immunosensor was applied in wastewater samples from Université Laval residences (Québec, Canada) through the load transfer resistance (R _ct) using [Fe(CN)₆]^3-/4- as a redox probe, and the average CIP concentration was found to be 2.90 × 10^-4 μg mL^-1. The observed R _ct changes presented a linear relationship from CIP concentrations of 10^-5 to 1.0 μg mL^-1, with detection and quantification lim
