Abstract
A 3D porous matrix makes an intriguing sensing platform, which can integrate functional guest molecules. Here, the first demonstration of a zinc compound/silicone hybrid foam is reported for amperometric sensing of glucose oxidase. The silicone foam is fabricated by a self-developed solid-filling-melting method. Two zinc-based polymers, Zn-Compound-1 and Zn-Compound-2, are synthesized. Zn-Compound-1 and Zn-Compound-2 are characterized by X-ray diffraction, X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, Raman spectroscopy, and X-ray absorption nearedge structure spectroscopy of carbon K-edge, oxygen K-edge, and zinc L-edge. Effective amperometric sensing of glucose oxidase is achieved by introducing Zn-Compound-1 or Zn-Compound-2 into the silicone foam, i.e., an increase of the concentration of the glucose oxidase led to an increase of detected current. This phenomenon can be explained by a possible mechanism of the formation of electron extra bands.
