介绍了一种用于食品质量控制的小型化安培厚膜生物传感器。它们易于制造，成本相对较低，便于用作一次性传感器。用丝网印刷技术替代了用戊二醛交联固定酶的方法，将基于石墨/TTF的糊状物酶层应用到厚膜电极上。举例说明了作为鱼类新鲜度指标的生物胺的测定以及果汁和葡萄酒中葡萄糖的测定。
Miniaturized amperometric thick film biosensors for applications in food quality control are described. Their ease of fabrication and relatively low cost facilitates their use as disposable sensors. As an alternative to the immobilization of the enzyme by cross-linking with glutaraldehyde, screen printing technology was used to apply the enzyme layer, a graphite/TTF based paste, to the thick film electrodes. Examples are presented of the determination of biogenic amines as an indicator of the freshness of fish, and of glucose in fruit juice and wine.
