Abstract

The development of advanced materials for biosensors has significantly enhanced the capability for efficient monitoring of uric acid, a critical biomarker for various diseases, including gout, cardiovascular disorders, and chronic kidney disease. This paper explores the novel application of dysprosium-doped calcium zirconate (DCZO) nanoparticles in electrochemical biosensors and supercapacitors for the first time. The DCZO-modified carbon paste electrode (MCPE) demonstrated a notable increase in sensitivity for uric acid (UA) detection, achieving a detection limit of 0.416 µM, with optimal performance at a pH of 7.0. The sensor exhibited linear responses to varying uric acid concentrations, scan rates, and dopamine (DA) interference, with R² values around 0.99. In supercapacitor applications, DCZO nanomaterials showed a remarkable specific capacitance of 224.8 F/g at a sweep rate of 2 mV/s, maintaining 86.36 % capacitance retention after 5000 cycles. These findings highlight the dual functionality of DCZO as an effective biosensor for uric acid detection and a robust material for supercapacitor applications.

期刊介绍： The Microchemical Journal is a peer reviewed journal devoted to all aspects and phases of analytical chemistry and chemical analysis. The Microchemical Journal publishes articles which are at the forefront of modern analytical chemistry and cover innovations in the techniques to the finest possible limits. This includes fundamental aspects, instrumentation, new developments, innovative and novel methods and applications including environmental and clinical field. Traditional classical analytical methods such as spectrophotometry and titrimetry as well as established instrumentation methods such as flame and graphite furnace atomic absorption spectrometry, gas chromatography, and modified glassy or carbon electrode electrochemical methods will be considered, provided they show significant improvements and novelty compared to the established methods.
