Synthesis of Cu(OH)F microspheres using atmospheric dielectric barrier discharge microplasma: a high-performance non-enzymatic electrochemical sensor

Abstract

In this study, Cu(OH)F microspheres suppported on a carbon cloth (Cu(OH)F MS/CC) were rapidly synthesized (at 90 V with 20 min) using an atmospheric dielectric barrier discharge microplasma (DBD). As a multifunctional electrochemical sensor for the detection of glucose (Glu), formaldehyde and hydrogen peroxide, it can accurately detect blood glucose levels in actual serum samples and can determine the contents of formaldehyde and hydrogen peroxide in water samples. Furthermore, it shows good sensitivity and selectivity, which confirmed the feasibility of the Cu(OH)F microsphere electrode for electrochemical sensing. This method was not only rapid and mild (at room temperature and atmospheric pressure) but also provided a promising route for the preparation of nanomaterials for electrochemical sensors.
