MAGNETIC DETECTION OF MERCURIC ION USING GIANT MAGNETORESISTIVE BASED BIOSENSING SYSTEM |
| 摘要 |
A system may include a magnetic sensor including a free magnetic layer and a fixed magnetic layer; a sample container disposed over the magnetic stack; a plurality of capture DNA oligomers on a surface of the magnetic biosensor within the volume defined by the sample container above the magnetic stack, wherein each of the plurality of capture DNA oligomers includes at least one thymine base configured to bind to an Hg2+ ion; a magnetic field generator configured to generate a magnetic field that influences the free layer; and circuitry configured to measure a resistance of the magnetic sensor. |
