Patent ID: 8128797

Claim:
An operating method for a microfluidic system, comprising the following steps: a) supplying of a carrier flow with particles of a first particle type suspended therein into the microfluidic system, b) charging of one or more individual electrical field cages in the microfluidic system with supplied particles of the first particle type, c) supplying of a carrier flow with particles of a second particle type suspended therein into the microfluidic system, d) charging of the one or more individual electrical field cages in the microfluidic system with the supplied particles of the second particle type so that at least one particle of the first particle type and at least one particle of the second particle type is present in the individual electrical field cages e) adhering of the particles of the first particle type in the individual electrical field cages on a channel wall after the charging and before the supplying of the particles of the second particle type.
