Urea impedimetric biosensor based on reactive RF magnetron sputtered zinc oxide nanoporous transducer

- Application and optimization of reactive RF magnetron sputtering for homogeneous nanoporous ZnO thin film formation.
- Exploiting nanoporous ZnO thin film as a good porous framework with large surface area/volume for having stable immobilized enzyme with minimum loss of activity.
- Application of impedimetric assessment for urea biosensing due to its rapidity, sensitivity, and repeatability.
