ABSTRACT:
A microfluidic system, particularly a microfluidic chip, with at least one operational channel, in which a fluid and/or the constituents contained therein are moveable in the direction of the operational channel by a driving force, particularly by using pressure, acoustic energy, or an electrical and/or a magnetic field. At least one measurement sensor used to measure a measurable value assigned to the fluid and derivable in the region of the fluid and at least one regulator is provided to regulate the driving force and/or a parameter that may be influenced by it, wherein the regulator is coupled with a measurement sensor and a device used to alter the driving force and/or the parameter that may be influenced by it. The microfluidic system further relates to a procedure to transport and guide a fluid and/or the constituents contained therein within a microfluidic system of the type described above. For this, the regulator regulates the driving force and/or the parameter that may be influenced by it by means of a measurement sensor to measure a parameter assigned to the fluid and derivable in the vicinity of the fluid and by means of a device used to alter the driving force and/or a parameter that may be influenced by it.
