摘要

基于一次性丝网印刷电极(spe)和亚硫酸盐氧化酶(SOx)酶，研制了一种安培亚硫酸盐生物传感器。该传感器灵敏度高(62 nA/ppm)，重现性好(RSD = 4%;N = 5)，线性范围为15- 1000ppm。成功地证明了该生物传感器在对虾养殖场样品中焦亚硫酸钠分析中的适用性。

SO2SAFE - Enzymatic SO2 Biosensor for Rapid Food Safety Monitoring

An amperometric sulfite biosensor was developed based on disposable screen printed electrodes (SPEs) and sulfite oxidase (SOx) enzyme. The developed biosensor shows good sensitivity (62 nA/ppm), reproducibility (RSD = 4%; n = 5) and a linear range of 15-1000 ppm. The applicability of the biosensor for the analysis of sodium metabisulfite in shrimp farm samples was demonstrated successfully.
