| titleOfInvention | Giant magnetoresistance-based biosensors |
| abstract | Disclosed is a system for detecting one or more target analytes which includes a resistor structure comprised of a substrate, a graphene-based nanocomposite material located on a surface of the substrate with the graphene-based nanocomposite material exhibiting one or more magnetoresistance properties. A surface of the nanocomposite material includes molecular sensing elements bound thereto which exhibit an affinity for binding with the target analytes. Electrodes are connected to the resistor structure connectable to a power source and a device for measuring a resistance across the resistor structure for sensing a giant magnetoresistance (GMR) value of the resistor structure. Included are magnetic colloidal nanoparticles exhibiting preselected magnetic properties with an outer surface of the magnetic colloidal nanoparticles being modified to allow interaction with the surface of the resistor structure resulting in a change in the GMR value of the resistor structure. The resistor structure is configured to be operably connected to a magnetic field generating device configured to apply a magnetic field to the graphene-based nanocomposite wherein the field has a magnitude in a range from greater than 0 to about 5 Tesla. A presence of target analytes in a vicinity of the surface of the resistor structure induces the interaction to occur by binding of the target analytes to the molecular sensing elements bound thereto causing a change in GMR value of the resistor structure. |
