Methods of construction and the behavior of microdisk and microsphere electrodes having radii down to 1000 and 200 A respectively and of microspheres having widths down to 250 A are discussed. The high steady state rates of mass transport and the low ohmic overpotentials allow the study of systems under simple steady state conditions as well as the study of many novel systems. It is shown that the rates of fast electrode reactions can be readily measured and the kinetics of reactions in solution coupled to electrode reactions are more easily determined than by relaxation methods using planar electrodes. Reactions can be examined in solvents using low or zero concentrations of support electrolyte as well as in low dielectric constant solvents.
