要約(日本語): Immunoassay is the detection of biological targets such as disease related proteins and cells, and is widely used for medical diagnosis. We have developed a liquid phase immunoassay technique using Brownian relaxation of magnetic markers. Using the technique and MR sensor, we performed the detection of a target called biotin without using the time-consuming washing process called BF separation. The sensitivity was estimated as high as 6 × 10^-16 mol/ml (or 0.6 fmol/ml) in terms of the molecular-number concentration.
