Description
The fabrication of polishable integrated dual submicrometer-sized electrodes has been reported. The electrode assembly consists of two closely spaced submicrometersized platinum disks. It has been accomplished by sealing and pulling platinum (Pt) wires in a θ glass pipet. Monitored by a microscope, the electrodes are polished on a 50 nm diamond lapping tape. Scanning electron microscopy (SEM) and cyclic voltammetry (CV) show that the electrodes are well sealed and are disks. The two submicrometer-sized Pt disk electrodes can work either independently or in the generation-collection model. The shielding effect, feedback effect, and generation-collection efficiency have been discussed.
