A novel lactate biosensor.
A novel disposable lactate biosensor was reported, which can measure the lactate in whole blood and other bio-fluids rapidly, accurately, expediently and directly. The biosensor was based on two kinds of electron mediator, the ferricyanide and the modified carbon nanotubes (CNT). Lactate oxidase (LOD) was coated on the electrodes. The sensor was fabricated by screen-printed techniques, the sample was supplied through capillary action and the volume was controlled by micro cavity. The liner range is 1~15 mmol/l, precision reaches 0.2 mmol/l . Compared with the respondence of sensor without carbon nanotubes, the characteristic of sensor include that is improved obviously.
