| Outline of Final Research Achievements |
We have developed a new binding method between magnetic markers and targets for biomedical applications. In this method, magnetic field is applied during the binding reaction so as to prevent the Brownian rotation of the markers in solution. As a result, magnetic moments of all the bound markers can be aligned in the direction of applied field. First, we determine the strength of the magnetic field that is necessary to align the magnetic moment. Next, we show that the magnetic properties of the bound markers, such as harmonic spectra and hysteresis loss, are significantly improved with this method. Finally, we apply the method to improve the performance of biosensing using magnetic markers.
