Abstract

The invention discloses an enzyme-free glucose sensor and a preparation method thereof. The method comprises the following steps: preparing a sodium tetrafluorocuprate nanoparticle-carbon material composite material from sodium tetrafluorocuprate nanoparticles and a carbon material; and modifying the sodium tetrafluorocuprate nanoparticles or the sodium tetrafluorocuprate nanoparticle-carbon material composite material with a noble metal electrode so as to obtain the enzyme-free glucose sensor. The enzyme-free glucose sensor is high in electrocatalytic activity, high in anti-interference performance, good in stability, simple in preparation method, low in cost and beneficial to large-scale preparation.

Description

Technical field[0001]The invention relates to the technical fields of chemical synthesis and biomedical engineering, in particular to a method for preparing an enzyme-free glucose sensor based on a composite material of sodium tetrafluorocuprate and carbon materials.Background technique[0002]The concentration of glucose is one of the important indicators for the diagnosis and treatment of diabetes. Therefore, accurate and rapid measurement of glucose is of great significance. At present, glucose sensors are mainly enzyme-type glucose sensors. Although the enzyme-type glucose sensor has the advantages of good selectivity and high sensitivity. However, the enzyme of the enzymatic glucose sensor is easily affected by the environment and loses its activity, resulting in unstable sensor. In addition, it is difficult to fix the enzyme, which leads to poor repeatability of the enzyme-type glucose sensor. Since the non-enzymatic glucose sensor does not rely on the activity of biological mol...
