Microelectrode array prodn. - by chemically metallising glass or thermoplastic materials

摘要

Prodn. of microelectrode arrays from glass or thermoplastic materials involves (a) contacting glass or thermoplastic powder with an activator and opt. reducing the activator, (b) metallising from a chemical metal plating bath, and (c) shaping by sintering or melting. Also claimed are (i) use of precious metal-contg. solns. for activating the surface of insulators prior to chemical metal plating to produce microelectrode arrays and (ii) use of chemical metal plating baths for prodn. of microelectrode arrays. USE/ADVANTAGE - The microelectrode arrays are esp. useful in electro-analysis and electro-synthesis. The arrays can be produced from a varity of metals and insulating materials using commercially available activator solns. and plating baths.
