  • Method of controlling a flow
    Patent number: 9486802
    Abstract: The present invention relates to a method of controlling a flow in a micro conduit system, and particularly a micro conduit system comprising one or more capillary-stop valves (6,6?) wherein the stopping ability of the capillary stop valve is overcome with the help of an acoustic wave source.
    Type: Grant

  • Method of producing a structure comprising a nanostructure
    Patent number: 9242408
    Abstract: The invention relates to a method by which a structure, e.g. a microstructure, is formed into a surface comprising a nanostructure during the fabrication of the structure. The method of fabrication of the structure is preferably embossing, and the invention thus describes methods by which a nanostructure is protected from being destroyed by the embossing process.

  • Generation of pulsating pressure waves, E.G. for cell lysis
    Patent number: 8637285
    Abstract: The present invention relates to a method by which a controlled source of heat (preferably a laser 3) generates a pulsating vapor bubble 4 in an enclosed liquid. The pulsating rate (the frequency) is preferably in the ultrasonic region, whereby cavitation occurs in the liquid. The cavitation effect will cause disruption of suspended components such as cells or bacterial spores. The ultrasonic disruption of cellular components is known as lysing by sonication.

  • CONTROLLED LIQUID HANDLING
    Publication number: 20110041922
    Abstract: The present invention relates to methods, devices and apparatuses for performing controlled liquid handling, and particularly, for performing controlled liquid handling in micro conduit systems. The invention involves pressing the liquid to be controlled against an enclosed gas to pressurize the gas, and controlling the flow of the liquid by controlling the subsequent evacuation of the pressurized gas. The present invention may be use for liquid handling in chemical and biomedical analysis systems.

  • Method And System For Determination Of Position
    Publication number: 20080128500
    Abstract: The present invention relates to a method and device for determining the position of an inserted cartridge in an apparatus, where knowledge of position relative to interfacing components of the apparatus is of importance when connecting said components to the inserted cartridge. The invention involves an optical scanning device in said apparatus and optical beam path influencing structures on or in said cartridge. Furthermore methods for reading cartridge type, stock number, bulk data or similar types of information, are also disclosed.
