A facile gold nanoparticles embeded hydrogel for non-enzymatic sensing of glucose

The assembly of nanoparticle into electrodes with precise structure and uniform core sizes is important for electrocatalysis. In this study, we reported on a simple strategy for in-situ preparation of gold nanoparticles embedded D-sorbitol hydrogel ( [email protected] ). D-sorbitol hydrogel with acyl hydrazide (D-gel) was synthesized and characterized. AuNP’s stable electronic structure, high surface coverage and good conductivity was achieved enabled [email protected] exhibits the enhanced electrocatalytic performance. The electrochemical results reveal that the catalytic progress is highly promoted by the [email protected] with a detection limit of 0.067 mM and detection range of 0.1–30 mM. The high enzymatic activity and stability provide the high possibility for the development of high value glucose sensors. This mechanistically novel strategy expands the scope of assembly of NPs method for the development of enhanced other electrochemical properties such as amperometric sensing and photcatalysis applications, as well as electrocatalysis.
