1. A method of detecting hydroxycarbamide in a solution, comprising:
contacting an electrochemical sensor with the solution;
applying a potential and irradiating the electrochemical sensor in the solution; and
measuring a Raman signal of the electrochemical sensor in the solution,
wherein an intensity of the Raman signal correlates with an amount of hydroxycarbamide in the solution,
wherein the electrochemical sensor comprises:
gold coated copper oxide circular nanoplates; and
a substrate,
wherein the gold coated copper oxide circular nanoplates are coated on the substrate.
