Conjugated hybrid nanostructured Cu2O-ZnO has been grown via the single-step coelectrodeposition (CED) technique. Though ZnO nanostructures grown alone by electrodepostion technique do not exhibit any glucose sensing, the CED-grown Cu2O-ZnO nanostructures show non-enzymatic glucose sensing and amperometric behavior with a good sensitivity of 441.2 μ A mM− 1 cm− 2, linear range of 0.02–1 mM and low detection limit of 0.13 μ M (S/N = 3) along with a fast response time (less than 3 s). The CED growth process leads to development of conjugated hybrid nanostructured Cu2O-ZnO that presents an excellent template for non-enzymatic glucose sensing.

单步共沉积技术制备的杂化纳米结构Cu 2 O-ZnO的非酶葡萄糖传感

共轭杂化纳米结构的Cu 2 O-ZnO通过单步共电沉积(CED)技术生长。虽然氧化锌纳米结构单独生长通过电沉积技术不表现出任何葡萄糖感测时,CED-生长的Cu 2 O形ZnO纳米显示非酶葡萄糖感测和安培计行为与441.2良好的灵敏度μ一个MM - 1厘米- 2,线性0.02-1毫范围和0.13检出限低μ M(S / N = 3)具有快速的响应时间(小于3秒)沿。CED的生长过程导致共轭杂化纳米结构Cu 2 O-ZnO的发展,该复合物为非酶葡萄糖传感提供了极好的模板。
