The invention relates to a micro-fluidic system including a fluid medium channel that holds a fluid medium containing particles in suspension. According to the invention, the fluid medium channel has an expanded section with an enlarged cross-section along part of its length, in order to reduce the flow speed to allow the analysis of the particles.
摘要:
A microsystem adapted for dielectrophoretic manipulation of particles in a suspension liquid wherein the microsystem has a channel with channel walls and a longitudinal extension. An electrode arrangement is present which has at least one microelectrode on at least one of the channel walls. This acts to generate a field barrier which crosses the channel at least partly. The microelectrode has a band-shape or has a multitude of straight electrode sections connected to each other. The band-shape has a predetermined curvature or the straight electrode sections are arranged with predetermined different angles so that the field barrier has a predetermined curvature relative to the longitudinal extension of the channel.

A rail assembly has an elongated upwardly open and elongated metal rail fixed to a car-body support and two confronting and inwardly concave flanges forming transversely inwardly directed faces and an elongated metal rail fixed to a motor-vehicle seat, captured between the flanges, and having two transversely outwardly directed faces generally complementary to and bearing with prestress outwardly on the inwardly directed faces. Respective friction-reducing layers on the faces allow the seat rail to slide smoothly in the body rail.
