Description
Summary:The development of highly sensitive hydrogen peroxide (H2O2) sensors of low cost with high stability is essential because of the significance of H2O2 in biological systems and its practical applications in different fields. The present work concerns the development of a highly sensitive flexible screen-printed amperometric H2O2 sensor. Hexacyanoferrates are known to be excellent sensing materials for nonenzymatic electrochemical sensing of hydrogen peroxide (H2O2), but they have certain limitations such as instability and low sensitivity. We have developed a method for the synthesis of porous cobalt hexacyanoferrate nanospheres (CoHCF-NSp’s) (
