This study introduces a method where a uniform HfO2 thin nanofilm (10 nm) is deposited on flexible carbon cloth (CC) using atomic layer deposition (ALD). This electrode replaces traditional glassy carbon electrodes and other metal electrodes used in sensor fabrication. The ALD technique is employed for the first time in the fabrication of nanomaterials for non-enzymatic uric acid detection, offering advantages such as a solvent-free, binder-free, and low-chemical synthesis process. Synergistic effect of CC and HfO2 active sites contributes to its benchmark performance as a uric-acid sensors. HfO2 structure can supply more reaction sites and ion diffusion pathways. ALD-derived HfO2 exhibit a significant number of oxygen vacancies due to the suboxide formation. These oxygen vacancies or defects act as charge-trapping sites, and when biomolecules are introduced, the film electrical conductivity is altered. The presence of a uniformly distributed, grainy porous structure explains the successful immobilization of uric acid on HfO?. The highly rough surface and large surface area of 200-HfO?/CC boost uric acid sensitivity by more than five times compared with cleaned CC. This research work confirmed that the sensor possesses high selectivity and good reproducibility, suggesting its ability for practical application. HfO2 with a nanofilm structure was chosen for the selective detection of uric acid for the first time, with higher stability and lower detection level (10 nM) (less than reported literature). Herein, this study presents a promising electrocatalyst for nonenzymatic uric acid detection and real-time monitoring of uric acid in human serum and urine for disease prevention. 2026 Elsevier B.V.
