A Self-Powered Photoelectrochemical Sensor Based on Direct-Laser-Writing Technology

设计了一种基于激光直写技术制备的二氧化钛/石墨烯(TiO_(2)/Graphene)为光阳极和铂电极为阴极的葡萄糖自供电光电化学传感器。探究了钛源添加量、纳米激光作用仪输出功率与溶液pH对传感器性能的影响。实验结果表明,所设计的传感器对葡萄糖浓度在50~500μmol·L^(-1)之间呈现出良好的线性关系,检出限为6.8μmol·L^(-1),最大输出功率为2.01μW·cm^(-2)。

A self-powered photoelectrochemical sensor for glucose with titanium dioxide/graphene(TiO_(2)/Graphene)as photoanode and platinum electrode as cathode,prepared by direct-laser-writing was designed.The effect of the addition of Ti^(4+)-OAA,nano laser instrument output power and pH of solution on the sensing were investigated.The results show that the designed sensor exhibits good linearity for glucose concentrations between 50μmol·L^(-1)and 500μmol·L^(-1),with a low detection limit of 6.8μmol·L^(-1)and a maximum output power of 2.01μW·cm^(-2).
