Abstract
Digital microfluidics system manipulates samples in liquid droplets within a gap of at least one disposable cartridge. It is also provides additional space for collecting and/or storing waste fluids in this digital microfluidics system. It includes at least one waste hollow which is fluidly connected with a gap of a disposable cartridge that includes a bottom layer with a first hydrophobic surface and a top layer with a second hydrophobic surface. The waste hollow is located next to at least one individual waste electrode that is positioned next to at least one individual electrode of an electrode array. Each individual waste electrode is operatively connected to a central control unit and covers in each case a waste electrode area.
