  • Stray field collector pad, and bio-molecule sensing module or biochip using the same
    Patent number: 8400146
    Abstract: Provided is a stray field collector (SFC) pad and a bio-molecule sensing module or a biochip using the same, and more particularly, a SFC pad, in which probe or detection molecules are attached to a plurality of magnetic labels (magnetic particles or beads) and they are bonded to complementary molecules to enhance a stray field sensor signal of the magnetic labels remaining in the vicinity of the sensor, and a bio-molecule sensing module and a biochip using the same. The provided is related to qualitative as well as quantitative detection of magnetic labels, and the SFC pad which can increase an effective surface area sensitive to the magnetic labels by probe-detection molecular bond in a magnetic biosensor and collect the resultant stray field can enhance sensitivity, accuracy and resolution of the magnetic biosensor.
