| 摘要 |
The present invention relates to a device and a method for clustering and subsequently distributing a plurality of paramagnetic particles (7) in a small volume liquid in a chamber, said chamber having a first wall (12) and an opposite second wall (13), said method comprising the steps of a) providing a liquid comprising the plurality of paramagnetic particles, b) subjecting the paramagnetic particles to a first magnetic field by means of a first field generating means (25) having first and second mutually spaced opposite poles and defining a first pole axis (26) extending between the poles, the field generating means being arranged relative to the first wall so that the first pole axis (a 1 ) forms an angle (v 1 ) of less than 60° with the first wall, c) moving the magnetic field in a first moving direction having a movement component in the direction of the first pole axis, or, alternatively, changing the polarity of the magnetic field one or more times, and, d) removing the magnetic field. |
