When a rotating magnetic field is applied to a spider web - shaped magnetic pattern, it can attract biomolecules labeled with superparamagnetic particles faster to the sensor. (sciencedaily.com)
The biomolecules labeled with superparamagnetic particles and the use of an external magnetic field enabled the movement of the biomolecules to be easily controlled and detected with an ultra-sensitive magnetic sensor. (sciencedaily.com)
«The largest superparamagnetic materials that we have been able to make before now were clusters of nanocrystals that were together about a thousand times smaller than these,» commented Dr. Chen. (sciencedaily.com)
