Discrete contact MR bio-sensor with magnetic label field alignment |
摘要 |
The invention describes a family of sensors for assaying macro-molecules and/or biological cells in solution. Each sensor has the form of a well (a hollow cylinder having a floor but no lid) or a trench whose walls comprise a plurality of GMR or TMR devices. Suitably shaped magnets located below each well's floor pull labeled particles into the well/trench and up against the inner wall where a field gradient orients them for optimum detection. Any unattached labels that happen to also be in the well/trench are removed through suitably sized holes in the floor.
