Application Comment Organism
analysis development of an amperometric biosensor for determination of glutathione, by immobilizing covalently a glutathione oxidase onto the surface of gold coated magnetic nanoparticles modified Pt electrode. The electrode shows maximum response within 4 s, when polarizes at +0.4 V, pH 7.0 and 25°C. There is a linear relationship between electrode response and glutathione concentrations in the range 5.0-4000 microM with a detection limit of 0.1 microM. The biosensor shows 50% loss in its initial activity after its 150 uses over a period 4 months. Glutathione concentration in hemolysated erythrocytes as measured by the present biosensor is 2.8 mM in apparently healthy persons unidentified
