Fabrication of Nickel Oxide Nanostructures with High Surface Area and Application for Urease-based Biosensor for Urea Detection |
초록 |
Uniform nanostructured nickel-based coordination polymer particles with multilayered morphologies (mL-NiCPPs) were successfully fabricated through a two-step heating process. To increase the surface area by reducing the size of mL-NiCPPs, pyridine and acetic acid were added as size modulators during the growth process. The resultant coordination polymer nanoparticles were then calcinated at a controlled temperature in order to produce nickel oxide nanostructures (mL-NiOs), which showed a relatively high BET specific surface area (112 m2/g) and a well-defined pore size (10 nm), hence exhibited significant potential for use in a variety of applications. The synthesized mL-NiOs were successfully deposited onto an indium tin oxide (ITO) serving as an efficient matrix for the immobilization of urease (Ur). The prepared bioelectrode showed a high sensitivity and a linear dependence of the current on the urea concentration. |
