IntroductionHeparin is a polysaccharide of glycosaminoglycanclass, which consists of repeating disaccharide units ofiduronic/glucuronic acid and glucosamine residues withmany biological functions[1,2]. Many methods havebeen proposed for the detection of heparin, includingUV-Vis spectrophotometry[3—7], the light scatteringtechnique[8], HPLC and electrophoresis[9,10]and flowinjection analysis[11],etc.. But there are few reportsabout the detection of heparin by means of an electro-chemical method[12].
