Carbon nanotubes(CNTs) and reduced graphene oxide(r GO) nanosheets were utilized to construct glucose biosensors in combination with gold nanowire arrays(Au NWAs), and microfluidic injection analysis driven by gravity force was used to investigate the performances of as-prepared glucose biosensors. The results demonstrated glucose biosensors based on carbon nanomaterials/Au NWAs presented excellent performance at low working potential of-0.2 V versus Ag/Ag Cl(3 mol/L KCl), such as high sensitivity, good anti-interference ability and high throughput(45 h~(-1)). The glucose biosensor based on glucose oxidase(GOx)–CNT–Au NWAs showed a wide linear range from 100 to 3,000 lmol/L with a sensitivity of 4.12 l A/cm~2 mmol/L. Furthermore, the linear range and sensitivity of GOx–r GO–Au NWAs-based glucose biosensor were 50–4,000 lmol/L and 8.59 l A/(cm~2 mmol/L), respectively, which were better than those of glucose biosensor based on GOx–CNT–Au NWAs,suggesting r GO nanosheets in combination with Au NWAs being a good platform for the construction of glucose biosensors.
Carbon nanotubes (CNTs) and reduced graphene oxide (r GO) nanosheets were utilized to construct glucose biosensors in combination with gold nanowire arrays (Au NWAs), and microfluidic injection analysis driven by gravity force was used to investigate the performances of as-prepared glucose biosensors. The results in glucose biosensors based on carbon nanomaterials / Au NWAs presented excellent performance at low working potential of-0.2 V versus Ag / Ag Cl (3 mol / L KCl), such as high sensitivity, good anti-interference ability and high throughput (45 h -1). The glucose biosensor based on glucose oxidase (GOx) -CNT-Au NWAs showed a wide linear range from 100 to 3,000 lmol / L with a sensitivity of 4.12 l A / cm ~ 2 mmol / L. Respectively, the linear range and sensitivity of GOx-r GO-Au NWAs-based glucose biosensor were 50-4,000 lmol / L and 8.59 l A / (cm ~ 2 mmol / L), respectively, which were better than those of glucose biosensor based on GOx-CNT-Au NWAs, suggesting r GO nanosheets in c ombination with Au NWAs being a good platform for the construction of glucose biosensors.
