✦ Synopsis

An amperometric enzyme sensor for the analysis of D-lysine is described. The sensor uses benzoquinone as mediator for electron transfer between immobilized D-amino acid oxidase and a glassy carbon electrode. A linear current response, proportional to D-lysine concentration in the range 1Β±10 mM, was observed. The inΒ―uence of oxygen, pH, and operating potential on the sensor performance were examined.

A mitochondria based amperometric biosensor was developed for the determination of L-glutamic acid. The biosensor was characterized using hexacyanoferrate(III) as the electrochemical mediator. The electrochemical behavior of the redox couple hexacyanoferrate(II)a(III) was improved by incorporating o
