MAGNETIC MANIPULATION DEVICE FOR MAGNETIC BEADS

摘要

The invention relates to a magnetic manipulation device (110) that can for example be integrated into a magnetic biosensor (100). The magnetic manipulation device (110) comprises at least one core structure (111) with an array of fingers (113) carrying coils (114) which can selectively be supplied with excitation currents by a controller (115). The core structure (111) has preferably a comb-like form and may for example extend along channels (12) of an exchangeable microfluidic device (10) in which a sample with magnetic target particles can be provided. The controller (115) is preferably adapted to generate moving activity patterns.
