A Single SnO2 Nanowire-Based Microelectrode

SnO₂ nanowires are synthesized via the chemical-vapor-deposition process using gold as the catalyst and characterized by X-ray powder diffraction, field-emission scanning electron microscopy, high-resolution transmission electron microscopy, and cathodoluminescence. Finally, a new type of microelectrode based on a single SnO₂ nanowire is fabricated. This microelectrode is expected to have promising applications in various chemical and biomedical nanosensors.
