AbstractThe unique properties of microelectrodes have been appreciated by electrochemists for some years, but the development of sensors which use these properties, in particular the high diffusion rates near the electrodes, has been slow. We consider first the dimensions which define microelectrodes. Silicon fabrication methods are well able to reach these, but the technology, outlined for a simple case of the production of an electrode array, is specialized. Progress in developing sensors will best be made by collaborations between engineering and electrochemistry groups. Examples of sensors and devices which utilize microelectrodes are given. Three depend on the high diffusion fluxes which can be established near microelectrodes, and one uses the fact that microstructures can be made which have features comparable in size to living cells. The resulting nonunilorm electric fields allow cells to be manipulated.
