Abstract
⺠A simple label-free aptasensor was developed by electrochemical impedance spectra. ⺠For the optimization, we designed and compared three different sensing interfaces. ⺠The sensor could detect as low as 100 nM cocaine without amplification or labeling. ⺠The aptasensor showed the potential application in biological fluid.
