Diabetes　is　a　series　of　metabolic　disorders,　such　as　sugar,　protein,　fat,　water　and　electrolytes.　It　is　caused　by　a　variety　of　pathogenic　factors,　such　as　genetic　factors,　immune　disorders,　microbial　infections　and　toxins,　leading　to　pancreatic　islet　dysfunction　and　insulin　resistance.　At　present,　drug　intake　and　real-time　blood　glucose　monitoring　are　the　main　methods　for　diabetic　patients　to　treat　diabetes.　At　present,　there　are　three　methods　for　detecting　blood　glucose　concentration:　color　method,　sensor　method　and　fluorescence　calibration　method.　Each　of　these　three　methods　has　its　advantages.　Among　them,　the　glucose　sensor　has　the　advantages　of　simple　instrument,　high　selectivity　and　sensitivity,　fast　detection　speed,　and　convenient　use.　In　the　past　ten　years,　electrochemical　glucose　sensors　have　made　great　progress.　The　glucose　electrochemical　sensor　uses　the　glucose　oxidase　fixed　on　the　surface　of　the　working　electrode　to　carry　out　the　Redox　reaction　with　the　glucose　in　the　tissue　fluid.　The　glucose　concentration　is　obtained　by　measuring　its　electrical　signal　through　a　certain　algorithm.　This　article　reviews　the　development　of　glucose　sensors　in　recent　years,　the　selection　of　glucose　sensor　materials　in　recent　years,　the　preparation　technology　of　materials,　and　the　development　prospects　of　glucose　sensors.　©　2022,　The　Author(s),　under　exclusive　license　to　Springer　Nature　Singapore　Pte　Ltd.
