Nanostructured Sensors for Non-Enzymatic Detection of Hydrogen Peroxide and Glucose

摘要

The problem of sensing and detection of small molecules, such as glucose or hydrogen peroxide, is of importance in a variety of areas including fuel cells, energy storage, organic synthesis, wastewater treatment, as well as medical, food or environmental analysis. Although enzymatic sensors of above-mentioned compounds possess high sensitivity, they suffer from instability, complicated modification procedures, and critical microenvironmental factors. Therefore, the development of new simple methods for fabrication of non-enzymatic electrochemical sensors offering good stability and selectivity is highly demanded.
