ABSTRACT
In this chapter, several methods for the fabrication of different types of amperometric tips suitable for scanning electrochemical microscopy (SECM) are described. We have also suggested some microelectrode fabrication techniques that have not been yet tested for SECM but may provide alternative ways for its tip preparation. Section 3.2.1 describes the techniques for the preparation of various metallic microelectrodes, including Pt, Pt-Ir, Au, Hg, W, and so on. The manufacture of carbon microelectrodes is presented in Section 3.2.2. Most of these tips are encapsulated in or supported with glass capillaries. Other coating materials and techniques are treated in Section 3.2.3.
