| 摘要 |
The description relates to a process for separating mixtures of microscopically small dielectric particles in suspension and a device for implementing the process. Prior art separation processes separate particle mixtures according to the differing mobilities of their components. This requires extensive measures to suppress convection in the suspension. In the process of the invention, the particle mixture is forced onto tracks by dielectrophoretic forces or by the flow of the suspension medium. An additional force which, for specific particle types, offsets the force driving the particles onto tracks, separates particles of these types out of the mixture. The device for implementing the process is suitable for system integration. It can be integrated on surfaces of silicon wafers economically and in large numbers. The device is suitable for isolating small particles like biological cells, cell organella, bio-molecules and organic dielectric particles.
