Sb-doped ZnO nanowires were synthesized via chemical vapor deposition method. Scanning electron microscopic, transmission electron microscopic, X-ray diffraction and energy dispersive spectrometer have been used to characterize the morphology and structure of the nanowires. The AlGaAs/GaAs HEMT drain-source current exhibited a fast response of about 1s when different concentrations of lactic acid solutions were added to the surface of lactate oxidase immobilized on the ZnO nanowires. The HEMT could detect a range of lactic acid concentrations from 3 pM to 30 μM. The biosensor exhibited good performance along with fast response, high sensitivity, and long-term stability. Our results demonstrate the possibility of using AlGaAs/GaAs HEMTs for lactic acid measurements and provide new further fundamental insights into the study of nanoscience and nanodevices.
