摘要
生物传感器作为一种新型的分析手段,具有选择性好、灵敏度高、分析速度快、成本低、能在复杂体系中进行在线连续监测等优点,己被广泛应用于临床医学、环境监测、食品等领域。近年来,将辣根过氧化氢酶(HRP)固定修饰在不同纳米材料修饰的电极表面,实现了HRP的直接电化学。通过电化学性能参数的对比可以了解不同纳米材料对HRP新型生物传感器性能的影响。
As a new analytical method,biosensor has the advantages of good selectivity,high sensitivity,fast analysis speed,low cost,on-line continuous monitoring in complex system and so on. Thus,biosensors have been widely used in clinical medicine,environmental monitoring,food and other fields. In recent years,horseradish peroxidase( HRP) has been immobilized on the surface of electrode modified by different nano-materials to achieve direct electrochemistry of HRP. The effects of different nano-materials on the performance of new generation HRP biosensors could be understood by comparing their electrochemical parameters.
