摘要：
This paper presents the development of a new optic fiber sensor for measuring ethanol concentration in real time, obtained by simultaneous immobilization of alcohol dehydrogenase and NAD + onto optical fiber by sol-gel technique in MTMOS/TEOS matrix. Biosensor was tested in a concentration range of 2-18% ethanol and the results were compared with standard spectrophotometric enzyme assay determinations, indicating that the sensor has a good functionality in the range of the analyzed concentrations.
