Lactate Oxidase and Glucose Oxidase Biosensor with Ultra-fine Au Particles
含超细Au颗粒的乳酸氧化酶和葡萄糖氧化酶生物传感器

Lactate oxidase and glucose oxidase are immobilized by gold nanoparticles with diameter of less than 10 nanometers. The experiments show that gold nanoparticles can increase the current response of the lactate oxidase electrode and glucose biosensor from tens nanoamperometer to thousands nanoamperometer. The function of gold nanoparticles to enzyme electrode is discussed.
