制备了双链和单链DNA修饰的玻碳电极,并且比较了抗坏血酸在裸电极和DNA修饰电极上的电催化性能,同时研究了扫描速度、pH对抗坏血酸在双链DNA修饰电极上的氧化性能的影响,计算了电子转移系数。
製備瞭雙鏈和單鏈DNA脩飾的玻碳電極,併且比較瞭抗壞血痠在裸電極和DNA脩飾電極上的電催化性能,同時研究瞭掃描速度、pH對抗壞血痠在雙鏈DNA脩飾電極上的氧化性能的影響,計算瞭電子轉移繫數。
제비료쌍련화단련DNA수식적파탄전겁,병차비교료항배혈산재라전겁화DNA수식전겁상적전최화성능,동시연구료소묘속도、pH대항배혈산재쌍련DNA수식전겁상적양화성능적영향,계산료전자전이계수。
In this work,dsDNA and ssDNA-modified glass carbon electrode were prepared,and the electrooxidation behavior of ascorbic acid on DNA-modified electrode was compared with that on the bare electrode.The influence of scanning rates and pH on the electrooxidation of ascorbic acid on dsDNA-modified electrode was investigated in detail,in which the electron transfer coefficient and the electrode reaction were discussed.
