Abstract
Nanoelectronic devices for the detection and quantification of biomolecules are provided. In certain embodiments, the devices are configured to detect and measure blood glucose levels. Also provided are methods of fabricating nanoelectronic devices for the detection of biomolecules.
Claims22
A method comprising:
- dispersing a plurality of nanostructures and a quantity of a biomolecule in an aqueous solution to thereby create a stable suspension of nanostructures and biomolecules;
- providing a substrate surface having an electrode surface thereon;
- and
- simultaneously depositing nanostructures and biomolecules from the stable suspension to at least the electrode surface to thereby immobilize the biomolecules on the substrate.

A nanoelectronic sensor comprising:
- a non-conductive substrate;
- a counter electrode and working electrode on said non-conductive substrate, said working electrode comprising a carbon conductive path and having a surface comprising a nanostructured carbon film;
- a quantity of a biomolecule configured to interact with a target species in contact with said nanostructured carbon film and immobilized on the nanostructured carbon film;
- an adhesive overlying the non-conductive substrate;
- and
- a sample well defined at least in part by a gap in the adhesive and configured for receiving a sample and contacting said sample with the biomolecule.
