Amperometric biosensor based on diamond paste for the enantioanalysis of L-lysine.

Abstract

An amperometric biosensor was proposed for the enantioanalysis of L-lysine. The biosensor is based on the impregnation of L-lysine oxidase in diamond paste. The potential used for the determination of l-lysine was 650 mV. The biosensor exhibited a linear concentration range between 1 and 100 nmol/L with a limit of detection of 4 pmol/L. The selectivity of… (More)
