Disposable electrochemical aptasensor based on carbon nanotubes- V2O5-chitosan nanocomposite for detection of ciprofloxacin

A novel electrochemical aptasensing transducer platform has been developed based on carbon nanotube (CNT)-V2O5-chitosan (CS) nanocomposites modified screen printed carbon electrode (SPCE) for the detection of ciprofloxacin. Using CNT-V2O5-CS/SPCE as the basal electrode transducer platform for the immobilization of the single-stranded DNA aptamer, and the electrochemical impedance spectroscopy (EIS) was selected for quantitative detection of...
