Valve for lab-on-a-chip systems, method for actuating and for producing valve

摘要

A substrate of a lab-on-a-chip system has two adjacent recesses, one serving as a flow channel and the other one being filled with an elastomer compound. In a first state, the elastomer compound and the substrate delimit the flow channel in a section. In a second state, the elastomer compound takes up the space in the recess in the substrate along a cross-section of the flow channel, thereby completely closing the flow channel. The substrate and the elastomer compound may be produced by injection molding techniques.

主权项

1. A valve for opening and closing a flow channel in a lab-on-a-chip system, comprising:
a support body having at least one first recess forming a flow channel and a second recess directly next to a subregion of the at least one first recess; an elastomer compound at least partially filling the second recess, the elastomer compound and the support body together forming boundary surfaces of the flow channel in the subregion of the at least one first recess in a first state, and the elastomer compound being deformed in a second state under pressure causing a cross section of the flow channel in the at least one first recess to be fully filled, so that the flow channel is closed; and a self-adhesive film covering the at least one first recess and the second recess in a liquid-tight and/or gas-tight fashion.
