Abstract

Hyperuricemia and its complications have emerged as the second largest metabolic disease worldwide after diabetes. Excessive uric acid causes gout, kidney disease, and arteriosclerosis. Gout tortures countless patients with inflammatory arthritis even teenagers. The traditional uric acid sensors suffer from complex, time-consuming, and inconvenient drawbacks, which desperately calls for a fast, efficient, and simple uric acid-sensing method. Herein, this work reported a wearable electrochemical uric acid sensor (WUS) based on cadmium sulfide (CdS)-graphene oxide (rGO) nanocomposites via hydrothermal method. The effects of composite ratio and catalyst loading amount on the UA-sensing performance were systematically studied. By tuning the loading quantity and doping concentration, a high sensitivity of 312.8 μA ∙ mM⁻¹ cm⁻² together with a wide linear detection range of 10 μM-1000 μM as well as low detection limits of 5.47 μM were achieved. The prepared sensor demonstrated good selectivity, reproducibility, and long-term stability.

期刊介绍： The Journal of Materials Science: Materials in Electronics is an established refereed companion to the Journal of Materials Science. It publishes papers on materials and their applications in modern electronics, covering the ground between fundamental science, such as semiconductor physics, and work concerned specifically with applications. It explores the growth and preparation of new materials, as well as their processing, fabrication, bonding and encapsulation, together with the reliability, failure analysis, quality assurance and characterization related to the whole range of applications in electronics. The Journal presents papers in newly developing fields such as low dimensional structures and devices, optoelectronics including III-V compounds, glasses and linear/non-linear crystal materials and lasers, high Tc superconductors, conducting polymers, thick film materials and new contact technologies, as well as the established electronics device and circuit materials.
