A β-CD/MWCNT-modified-microelectrode array for rapid determination of imidacloprid in vegetables

This work introduces a β-cyclodextrin/multi-walled carbon nanotube (β-CD/MWCNT)–modified microelectrode array (MEA) for rapid determination of imidacloprid in vegetables. The MEA, fabricated on a silicon wafer, contains 20 parallel-connected working electrodes, a counter electrode and a reference electrode. The MWCNT is drop-casted onto the working electrode area, and β-CD is decorated onto the MWCNT layer with electropolymerization....
