Nanoscale Spintronic Chemical Sensor

Description:

Reference #:  00606

The University of South Carolina is offering licensing opportunities for this novel device used in chemical detection.

Invention Description:

This technology is a hybrid spintronic device for converting chemical absorption into a change in magnetoresistance. This technology uses a novel magnetic material which depends on the attachment of an organic structure to a metallic film for its magnetism. Changes in the chemical environment lead to absorption on the surface of this organometallic bilayer and thus modify its magnetic properties. The change in magnetic properties, in turn, leads to a change in the resistance of a magnetoresistive structure or a spin transistor structure, allowing a standard electrical detection of the chemical change in the sensor surface.

Advantages and Benefits:

This technology runs on a low amount of power and is portable, unlike devices that can perform similar detection. It also can be used to detect a multitude of atmospheric chemicals. Furthermore, it can be adjusted to be sensitive to a particular species of chemical.

Potential Applications:

This technology may be employed in nearly any chemical detection applications and could also incorporate a magnetic field sensor for magnetic data storage applications such as mass storage or magnetoresistive RAM.
