Metal dispersed carbon paste elctrodes were fabricated, and their electrochemical properties were investigated. Among various metal dispersed carbons, platinum-dispersed carbon paste electrode showed most efficient electrocatalytic characteristics. The overpotential for the the oxidation of NADH was alsoenhanced. Based on these electrocatalystic observations, L-lactate biosensor using L-lactate dehydrogenase was constructed to evaluate its peformance in terms of sensitivity and stability.
