DISTRIBUTION OF PARTICLES IN CHAMBER BY APPLICATION OF MAGNETIC FIELD

摘要

The present invention relates to a device and a method for clustering and subsequently distributing a plurality of paramagnetic particles in a small volume liquid in a chamber, said chamber having a first wall and an opposite second wall, 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 having first and second mutually spaced opposite poles and defining a first pole axis extending between the poles, the field generating means being arranged relative to the first wall so that the first pole axis (a₁) forms an angle (v₁) 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.
