Example of a lab-on-chip technology for biological applications. A multiplicity of branched microfluidic channels (between white double lines) bear a variety of different electrode layouts (black fine lines) for applications like cell imprinting, cell fusion or cell separation. Fluidic connection is realized on the backside, electronic connection via the 2×30-pole interfaces (green boards). For size comparison a one Euro-coin at the lower left corner. Kindly provided by M.
