摘要： A microfluidic device has a device body, wherein the device body defines a microfluidic reactor and a pressure control system therein, the pressure control system being arranged proximate the microfluidic reactor. The microfluidic device also has a fluid-permeable membrane arranged between the microfluidic reactor and the pressure control system, the fluid-permeable membrane having a surface area and thickness such that a fluid can pass from a high pressure side to a low pressure side of said fluid-permeable membrane during operation of the microfluidic device to at least one of change a pressure in the microfluidic reactor in a preselected manner, to maintain a substantially constant pressure in the microfluidic reactor, to change a composition of fluids in the microfluidic reactor, or maintain a composition of fluids in the microfluidic reactor. A method on performing chemical reactions includes introducing a plurality of chemical substances into a microfluidic reactor, wherein the microfluidic reactor has a fluid-permeable membrane between at least a portion of the microfluidic reactor and a microfluidic pressure control system; and at least one of pressurizing with a fluid or evacuating a region of the pressure control system proximate the fluid-permeable membrane to cause fluid to pass through the fluid-permeable membrane in a predetermined manner in order to cause a predetermined effect on a chemical reaction in the microfluidic reactor.
