摘要： A disposable cartridge configured as a digital microfluidics system for manipulating samples in liquid portions having a cartridge accommodation site and a central control unit for controlling selection of individual electrodes of an electrode array located at the site and for providing plural electrodes with individual voltage pulses for manipulating liquid portions by electrowetting. The cartridge has a hydrophobic working surface and a rigid cover with a second hydrophobic surface, the hydrophobic surfaces facing each other and being separated in parallel planes by a gap. The cartridge has plural pipetting guides for safe entering/withdrawing liquids into/from the gap with a pipette tip. At least one of the pipetting guides provides an abutting surface sealingly admittable by a counter surface of a pipette tip, located at a pipetting orifice that reaches through the rigid cover, and configured to prevent a pipette tip from touching the hydrophobic working surface.

摘要： A digital microfluidics system for manipulating samples in liquid droplets within a gap between a first hydrophobic surface of a bottom layer and a second hydrophobic surface of at least one disposable cartridge. Disposable cartridges comprise a body and/or a rigid cover plate. The bottom layer of each disposable cartridge is a flexible film that is sealingly attached to the body or plate. The cartridge has no spacer between the first and second hydrophobic surfaces. When using these cartridges, the bottom layers configured as a working film for manipulating samples in liquid droplets thereon, is placed on an electrode array of a digital microfluidics system. The array has individual electrodes. The digital microfluidics system also comprises a central control unit for controlling the selection of the individual electrodes of the electrode array and for providing these electrodes with individual voltage pulses for manipulating liquid droplets by electrowetting.

摘要： A digital microfluidics system with electrodes attached to a substrate and covered by a hydrophobic surface, and a control unit for manipulating liquid droplets by electrowetting; providing in close proximity to electrodes a magnetic conduit for directing a magnetic field of a backing magnet to the first hydrophobic surface; providing on the hydrophobic surface a liquid droplet that has magnetically responsive beads; moving by electrowetting the liquid droplet with the magnetically responsive beads until a part of which is placed atop of the magnetic conduit; actuating the backing magnet of the magnetic conduit and attracting/concentrating magnetically responsive beads; and while actuating the backing magnet, moving by electrowetting the liquid droplet with decreased number of magnetically responsive beads away from the specific magnetic conduit. Also disclosed are a method for suspending magnetically responsive beads in liquid portions or droplets in digital microfluidics and a disposable cartridge to carry out the methods.

摘要： A disposable cartridge (2) for use in a digital microfluidics system (1) comprises a bottom layer (3) with a first hydrophobic surface (17'), a rigid cover plate (12) with a second hydrophobic surface (17"), and a gap (6) there-between. The bottom layer (3) is a flexible film laid onto an uppermost surface (52) of a cartridge accommodation site (8) of a digital microfluidics system (1), attracted to and spread over the uppermost surface (52) by an underpressure in an evacuation space (46). The disposable cartridge (2) may be assembled at a cartridge accommodation site (8), a lower surface (48') of the rigid cover plate (12) and the flexible bottom layer (3) then are sealingly attached to each other by mutual contacting. The assembled disposable cartridge (2) is removed from the cartridge accommodation site (8) in one piece that comprises the bottom layer (3), the plane rigid cover plate (12), and the gap (6) that potentially comprises samples and processing fluids. The digital microfluidics system (1) comprises a base unit (7) and a cartridge accommodation site (8) with an electrode array (9) that comprises a number of individual electrodes (10). The digital microfluidics system (1) comprises a central control unit (14) for controlling the selection of the individual electrodes (10) and for providing these electrodes (10) with individual voltage pulses for manipulating liquid droplets within the gap (6) of the cartridge (2) by electrowetting.
