近年来,应用丝网印刷技术,并通过化学交联的方法将酶用牛血清白蛋白和戊二醛交联固定并修饰到电极表面来制备微型生物传感器是一种研究较多的方法。其主要的优点是制作方便,成本低廉,通过工艺上的控制能够使同一批电极之间的互换性较好,从而达到批量制作和产业化的要求。本文应用主客体包络的方法,使作为电子传递中介体的二茂铁包络在 In recent years, the use of screen printing technology, and by chemical cross-linking method of bovine serum albumin and glutaraldehyde cross-linked fixed and modified to the electrode surface to prepare micro-biosensors is a more studied method. Its main advantage is easy to manufacture, low cost, through the process control can make the same batch of electrodes between the interchangeability is better, so as to achieve batch production and industrialization requirements. In this paper, the method of host-guest envelope is used to make the ferrocene envelope as an electron mediator
