摘要: A flow-injection chemiluminescence (CL) biosensor for the determination of total d-amino acid is described in this paper. d-amino acid oxidase was immobilized onto amine-modified silica gel via glutaraldehyde activation and packed in a column. The other analytical reagents, including luminol and ferricyanide, were electrostatically co-immobilized on an anion-exchange column. d-amino acid was sensed by the CL reaction between hydrogen peroxide produced from the enzyme column and luminol and ferricyanide, which were …
