1. A method to detect a change of an electrochemical parameter in a solution, comprising:
- introducing at least one diamond structure, including a color center below a surface of thereof, into the solution;
applying an electromagnetic pump field to the at least one diamond structure;
functionalizing the at least one diamond structure to thereby enhance detection of the electrochemical parameter;
monitoring a radiative state of the color center by measurement of an emission of photons from the color center; and
detecting the change of the electrochemical parameter of the solution based on a predetermined correlation between the measurement and the electrochemical parameter.
