Protein Detection with Potentiometric Aptasensors: A Comparative Study between Polyaniline and Single-Walled Carbon Nanotubes Transducers

<table>Potentiometric response of the TBA-modified PANI- and SWCNT-based sensors to thrombin. Concentration range is 0,5 nM–800 nM in both cases. The inset shows average calibration curves for the PANI and the SWCNTs potentiometric sensors against thrombin with the corresponding error bars.</table>
