采用四硫富瓦烯（ＴＴＦ）作为黄嘌呤氧化酶与玻碳电极之间的电子传递体，通过牛血清白蛋白和戊二醛交联剂，把黄嘌呤氧化酶固定在Ｎａｆｉｏｎ－ＴＴＦ修饰玻碳电极上，制备成次黄嘌呤传感器。该传感器的线性范围为１．０×１０－５～７．５×１０－４ｍｏｌ／Ｌ，响应时间小于６０ｓ。
Tetrathiafulvalene (TTF) was used as the electron mediator between xanthine oxidase and the glassy carbon electrode. Xanthine oxidase was immobilized on Nafion-TTF modified glass by bovine serum albumin and glutaraldehyde crosslinking agent Carbon electrode, prepared hypoxanthine sensor. The sensor linear range of 1.0 × 10-5 ~ 7.5 × 10-4mol / L, the response time of less than 60s.
