Abstract:
A microfluidic system for directing subject materials to a next processing region comprising:a first channel having a first processing region for accommodating a first processing of said subject materials; a second channel in fluid communication with said first channel, said second channel having a plurality of processing regions including said next processing region; and a gas generator having a gas-forming area such that a formation of gas in said gas-forming area generates a pressure which forces said subject materials from said first channel to said next processing region, said next processing region being configured to accommodate a next processing of said subject materials, said gas generator including a plurality of discrete quantities of a gas-forming material in said gas-forming area and including a heating mechanism which is controllable to selectively activate individual said discrete quantities, thereby enabling selectivity in forming a level of said pressure.
