| 摘要 |
<p>The invention relates to a dielectrophoresis system of handling dielectric particles, particularly biological cells, which are suspended in a medium and subjected to the action of an alternating electrical field. The distribution of said field is made non-uniform using a regular network (R) of electrodes (E1, E2) which can define local areas (L) where the electrical field is minimum in order to concentrate particles in said local zones (L) as a result of the action of the negative dielectrophoresis forces. The inventive system is characterised in that the network (R) of electrodes (E1, E2) is formed on the surface of a multi-layered support (1). Moreover, said system is characterised in that the electrodes (E1, E2) in the network (R) having the same polarity are linked to a common power supply contact (P1, P2) via two networks (R1, R2) of strip conductors (C1, C2) which are formed at an intermediary level located below the network (R) of electrodes.</p> |
