A non-enzymatic disposable electrochemical sensor based on surface-modified screen-printed electrode CuO-IL/rGO nanocomposite for a single-step determination of glucose in human urine and electrolyte drinks

A novel designed device of CuO-IL/rGO-modified SPCE combined with NaOH-coated wax-printed paper was developed as a non-enzymatic glucose sensor with single-step sample loading in human urine and electrolyte drinks via portable potentiostat.
