Schematic description of newly developed 3D microarray technology. (a) The 3D microarray (PamChip) with the four array format (left), an array with a diameter of 45 mm (middle), and a set of oligo DNA probes immobilized with 120 μm diameter (right). (b) The partial top (left) and cross section view (right) of multi-porous substrate within PamChip. (c) FD10 microarray system with functions of hybridization, washing, fluorescence imaging and image analysis, which are integrated and performed semi-automatically.
