In Situ Growth of Ni(OH)2 Nanoparticles on 316L Stainless Steel Foam: An Efficient Three-dimensional Nonenzymatic Glucose Electrochemical Sensor in Real Human Blood Serum Samples

For the first time, nickel hydroxide nanoparticles (Ni(OH)2 NPs) grown on 316L stainless steel foam were used as a non-enzymatic electrochemical glucose sensor. The Ni(OH)2/SSF-316L was elaborated by applying a simple ultrafast CV method without nickel salts addition. Ni(OH)2/SSF-316L was characterized by SEM and XRD. The electrochemical behavior was investigated by CV, EIS, and amperometric measurements. The fabricated sensor revealed higher sensitivity 1062 μA mM 1cm 2, wide linear range from 1.0 μM to 4.0 mM with a low detection limit of 2.0 μM and good selectivity. In addition, real sample analysis was performed for controlled glucose in real blood serum.
