Title
(EN) Microfluidic system with integrated permeable membrane
Abstract
(EN)

A microfluidic system for performing chemical reactions or biochemical, biological, or chemical assays utilizing a microfabricated device or “chip.” The system may include, among others, an integrated membrane fabricated from a chemically inert material whose permeability for gases, liquids, cells, and specific molecules, etc. can be selected for optimum results in a desired application.
