Abstract
A detection method and sensors are provided for the rapid detection of chemicals, biological and non-biological, and a wide range of viruses using magnetic tunnel junction-based molecular spintronics devices (MTJMSD) that produce unique magnetic resonance signals before and after interacting with target chemical, biochemical, viral, and other molecular agents.
Claims19
A molecular tunnel junction based molecular spintronics device comprising:
- a substrate having an upper surface;
- a ferromagnetic structure appended to the top of the upper surface of the substrate and extending in a direction perpendicular to said upper surface, wherein the ferromagnetic structure comprises:
- a ground layer,
- a first ferromagnetic layer appended to a top surface of the ground layer;
- a first insulator layer appended to a top surface of the first ferromagnetic layer;
- a second ferromagnetic layer appended to a top surface of the first insulator layer;
- a material attached to the first ferromagnetic layer or the second ferromagnetic layer, said material selected from a virus sensor or a molecular detector, and
- a waveguide comprising a pair of ground lines flanking said ferromagnetic structure.
