CARBON NANOSTRUCTURE ELECTROCHEMICAL SENSOR AND METHOD

摘要

Carbon nanostructures may be protected and functionalized using a layer-by-layer method whereby functional groups on the carbon nanostructure surface may be further derivatized to incorporate additional functional moieties. Carbon nanostructures functionalized using such a layer-by-layer method may be used to disperse, sort, separate and purify carbon nanostructures and may be used as sensing elements such as voltammetric, amperometric, and potentiometric pH sensors or as biometric sensing elements and electrodes and intracorporeal sensors and electrodes.

1. A method for measuring pH in an environment comprising the steps of:
providing an electrochemical sensor, the sensor having a reference electrode and a sensing electrode, the sensing electrode disposed between a first contact and a second contact; applying a potential across the reference and sensing electrodes; measuring current resulting from the applied potential; and determining pH in the environment as a function of the measured current.
