The detection method of glucose concentration has attracted much attention in the fields of medicine,food, bioengineering and so on. Compared with the currently used sensors, the enzyme-free glucose sensor is a promising method because of its flexible detection, stability, low cost, and reusability. With the study of functionalization and refinement of modern nanomaterials and the study of electrocatalytic reaction mechanism, the enzymefree glucose sensor can quickly and stably detect blood glucose concentration in the future, and promote the progress of medicine. Therefore, this paper mainly reviews the research status of nanomaterials in enzyme-free electrochemical glucose sensors in recent years from three aspects: metal nanomaterials, non-metallic nanomaterials and metal oxide nanomaterials, and introduces the excellent properties of new nanomaterials in enzyme-free glucose sensors. performance, and the future development trend and direction are prospected.
