A novel Molecularly Imprinted Sensor based on Gold Nanoparticles/Reduced Graphene Oxide/Single-Walled Carbon Nanotubes Nanocomposite for the Detection of pefloxacin
A molecularly imprinted electrochemical sensor was developed for the detection of pefloxacin. Themolecularly imprinted polymer (MIP) was prepared via electrodeposition on the surface of a goldnanoparticles/reduced graphene oxide/single-walled carbon nanotubes modified glass carbon electrodeby incorporation of pefloxacin as a template molecule during the electrochemical polymerization of ophenylenediamine. The namocomposite of gold nanoparticals/reduced graphene oxide/single-walledcarbon nanotubes was obtained by one-step electrochemical reduction. Differential pulse voltammogram(DPV) showed a linear pefloxacin concentration range from 5.0 × 10-7 mol/L to 2.0 × 10-5 mol/L, andthe detection limit was 1.6 × 10-8 mol/L. The sensor also showed high selectivity, stability andreproducibility. Moreover, the sensor was successfully applied in the analysis of actual milk sampleswith satisfactory recovery rates.
