Abstract
A flow cell and a method for connecting components of a microfluidic flow cell, in particular for integrating component parts into a carrier structure of the flow cell, in which a gap is formed between the components to be connected. The gap is filled with a solvent. The material of at least one component bordering the gap dissolves in the solvent and the material completely fills the width of the gap and partially fills the height thereof after evaporation of the solvent.
Claims10
A microfluidic flow cell, comprising:
- a carrier structure having a pocket having a bottom with an opening;
- a component arranged in the pocket at a distance from a wall of the pocket so as to form a gap between an entire outer surface of the component and the wall, the gap having a bottom formed by the bottom of the pocket and an opening opposite the bottom;
- and
- a connection structure obtained by dissolving material from at least one of the component and the carrier structure by a solvent in the gap and settling of the material from the solvent toward the bottom gap as a result of evaporation of the solvent through the opening, wherein the connection structure is formed by settled material that completely fills the gap from the bottom of the gap up to at least a portion of a height of the gap, wherein the connection structure has a layered configuration.
