ABSTRACT
Nanostructured inorganic materials have potential advantages as glucose-sensing elements in diabetes care, thereby circumventing the need for expensive enzymatic agents. However, many nonenzymatic sensors face challenges related to selectivity and reliability, reducing their efficacy in body fluids. 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 (â¼104%) 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.
