Abstract

Currently, Continuous Glucose Monitors (CGMs) rely on the glucose oxidase enzyme. However, the stability of enzymes is greatly affected by factors such as temperature, which in turn deteriorate the accuracy of CGMs. Here, we introduce the first swellable hydrogel microneedle (MN)-based biosensor for continuous, real-time, enzyme-less, and pain-less glucose sensing. Using a MN-based three electrode system, we detected concentration of glucose ranging from 0 to 20 mM in a skin-mimicking phantom gel.
