Facile synthesis of layered CuS/RGO/CuS nanocomposite on Cu foam for ultrasensitive nonenzymatic detection of glucose

CuS/RGO/CuS nanocomposite of lamellar structure was in-situ-grown on Cu foam through a one-pot hydrothermal approach. As-prepared CuS/RGO/CuS/Cu was directly served as a nonenzymatic glucose sensor with an ultrahigh sensitivity.106
