SO2SAFE - A FAST AND ACCURATE ELECTROCHEMICAL BIOSENSOR FOR SULPHITE ANALYSIS IN FOOD INDUSTRY

摘要

Enzyme-based biosensors are widely used in many applications such as health care, food safety and environmental monitoring. However, the implementation of many of these applications is strongly hindered by their limited stability on time. This paper reports a disposable electrochemical biosensor based on screen-printing technology for the easy, fast and accurate determination of sulphite in shrimp farming, which shows good sensitivity (62 nA/ppm), reproducibility (RSD = 4%; n = 5), and a high storage stability (8 months).
