Figure 1

Schematic illustration of the fabrication process of the competitive sensing platform.

Process (A) and (B) respectively represents the preparation of electrode modified with Cd2+@TiO2-anti-DXM and Cd2+@TiO2-anti-DXM containing DXM of different concentration. Under light illumination, the changed current due to various amounts of Cd2+@TiO2-anti-DXM immobilized on electrode surface is recorded as the sensing signal.
