“…Wang [8] described a fluorescent sensor for detecting iodine ions based on a CH-ZnS/Mn composite film. Hwang [9] presented his research on CH-ZnS/Mn nanocrystals as sensing materials for fluorescent sensors to detect copper (II) ions in aqueous solutions. However, to the authors' knowledge, there is no report on using these materials for electrochemical glucose sensing.…”

A typical glucose sensor is a glucose oxidase (GOx) enzyme-based sensor due to its high sensitivity and selectivity. However, it has difficulty activating and stabilizing the enzyme. To enhance the stability of GOx-based sensors, chitosan is added to ZnS-doped Mn nanoparticles. Chitosan stabilizes the ZnS-doped Mn particles and can induce charge processes such as creation, transfer, and separation at the polymer interface and nanoparticles' interface. Hence, it is a strong candidate for electrochemical glucose sensing applications. This letter reports the impedance biosensor based on ZnS-doped Mn-capped chitosan nanomaterials and microinterdigitated electrodes. The glucose sensors' high sensitivity, accuracy, and stability are obtained in the range of 2 to 10 mM. In addition, an application of the Canny edge detection to enhance the limit of detection is demonstrated using experimental data.
