Busnaina and Somu Awarded Patent

MIE Professor Ahmed Busnaina & Director of the Kostas Nanoscale Research Center Siva Somu were awarded a patent for “Single-walled carbon nanotube biosensor for detection of glucose, lactate, and urea”.

Abstract Source: USPTO

A single-walled carbon nanotube-based micron scale multiplex biosensor is provided that enables the detection of glucose, lactate, and urea. The sensor is based on modification of semiconducting single-walled carbon nanotubes using a linker that non-covalently associates with the nanotubes and covalently couples to an enzyme. Reaction of a physiological substrate with the enzyme results in increased resistance of the nanotubes within the sensor. The sensor is suitable for use in patient monitoring, particularly in a clinical setting. Incorporation of read out electronics and an RF signal generator into the sensor device enables it to communicate to a relay station or remote receiver. Methods are also provided for fabricating the biosensor device and using the device for detection.
