%X A versatile strategy for electrochemical determination of glycoalkaloids (GAs) was developed by using a carbon nanotubes-phenylboronic acid (CNTs-PBA) modified glassy carbon electrode. PBA reacts with ¦Á-solanine and ¦Á-chaconine to form a cyclic ester, which could be utilized to detect GAs. This method allowed GA detection from 1 ¦ÌM to 28 ¦ÌM and the detection limit was 0.3 ¦ÌM. Affinity interaction of GAs and immobilized PBA caused an essential change of the peak current. The CNT-PBA modified electrodes were sensitive for detection of GAs, and the peak current values were in quite good agreement with those measured by the sensors.
