CARBON NANOSTRUCTURE SENSOR AND METHOD FOR BIOMOLECULE SENSING

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 voltametric, amperometric, and potentiometric pH sensors or as biosensors, biometric sensing elements and electrodes and intracorporeal sensors and electrodes.

1. A device for measuring a biological target species in a fluid comprising:
a reference electrode in communication with a fluid; a sensing electrode in communication with the fluid and disposed between a first electrical contact and a second electrical contact; wherein the sensing electrode includes one or more carbon nanostructures functionalized with a chemically stable moiety that responds to a biological target species in the fluid when a potential is applied across the first and second electrical contacts to provide a current correlating to a concentration of the target species in the fluid.
