Iridium oxide-based non-enzymatic glucose sensor: Superior electro-catalytic performance in biological environmental media

In this study, we introduce an Iridium oxide (IrO2)-based non-enzymatic glucose sensor. This sensor demonstrates exceptional electro-catalytic properties in human serum, characterized by high sensitivity (638 μA μM-1cm2) and a consistent recovery rate (∼104%) across 15 cycles in saline. Furthermore, its impressive performance in human serum, as evidenced by a low relative standard deviation (RSD <1.57%), underscores its applicability in biological matrices such as interstitial fluids. Overall, the IrO2 sensor is a promising, highly reversible, economical, and simple method for detecting glucose in continuous monitoring systems.PMID:38604481 | DOI:10.1016/j.envres.2024.118772
