Abstract:
A micro-valve for controlling fluid flows and a sealing device for sealing off cavities in a microfluid system, in particular in a lab-on-a-chip system, and also a method for the production thereof. A valve body or a sealing element bears with a sealing surface against a sealing surface of a substrate, the valve body or the sealing element is pressed with the sealing surface thereof in a fluid-tight manner against the sealing surface of the substrate by means of a pressure-exerting ring, and the pressure-exerting ring is cohesively connected to the substrate. The pressure-exerting ring and/or the valve body or the sealing element are at least partially elastic.
