A panticular NO microelectrode has been developed,possessing good selectivity, sensitivity, and mechanical strength, and a novel test technique of NO microelectrode has been established. Neurotransmitters including monoamines, amino acids, peptides, and related bioactive substances such as calcium, magnesium, kalium, natrium and indole substances in brain have been studied by capillary electrophoresis with electrochemical detection. Some problems in analysis of actual samples have been solved, such as micro sample injection and the joint of CE-ED with micro-dialysis.
