主 题：Glucose TiO_(2) Enzyme-free Photocatalysis Electrochemical biosensor
摘 要：A simple one-step hydrothermal method is used to prepare an enzyme-free photoelectric combined glucose sensor based on TiO_(2)NRs/FTO with low cost,sample two-electrode,and excellent *** 380 nm light(0.5 mW cm^(−2))irradiation and a positive voltage,holes are accumulated on TiO_(2)NRs surface,catalyzing glucose and forming a photocurrent without the need for an enzyme,such as Glucose oxidase(GOx).The designed sensor exhibits high sensitivity(about 0.96μA mM^(−1)cm^(−2),without GOx)and excellent linear relationship in the glucose concentration range of 5–15 mML^(−1).The prepared glucose sensor performs better with a sensitivity of 1.48μA mM^(−1)cm^(−2)when a certain amount of GOx is mixed in the detected *** addition,the sensor has excellent anti-interference resistance to non-reducing chitosan and reducing ascorbic acid with short response time(less than 5 s);thus,it can be used in quick detection with a double electrode *** sensing device has the advantages of simple fabrication,easy storage,and reusability;therefore,it can be very promising in the portable and rapid monitoring of human blood glucose levels.
