Abstract
A system for measuring pH includes a substrate and a sensor medium on the substrate. The sensor medium includes at least one oxidized carbon nanostructure and optionally at least one composition immobilized on the at least one oxidized carbon nanostructure. The at least one composition has at least one property that depends on pH. The system further includes at least one measurement system to measure a property of the sensor medium.
