Abstract

A novel enzyme-based biosensor for glucose detection is successfully developed using layer-by-layer assembly technology. The introduction of commercially available SiO<sub>2</sub> was found to be a facile way to improve overall electrochemical stability. After 30 CV cycles, the proposed biosensor could retain 95&#x0025; of its original current. The biosensor presents good detection stability and reproducibility with the detection concentration range of 1.96&#x2009;&#xd7;&#x2009;10<sup>&#x2212;9</sup> to 7.24&#x2009;&#xd7;&#x2009;10<sup>&#x2212;7</sup>&#x2009;M. This study demonstrated that the hybridization of cheap inorganic nanoparticles was a useful method in preparing high-performance biosensors with a much lower cost.
