The assembled setup of a battery-operated, programmable, portable, and integrated OoC platform. a Top view of the platform with functional components labeled. b Isometric-view of the platform whose dimensions are 290 mm long, 240 mm wide and 220 mm tall (37 mm box + components on top), with a total weight of 4.8 kg. All fluidic components were placed on the box. The control electronic components and the batteries were inside the box. c The platform was mounted on an upright microscope (Motic, BA310Met-T). The microfluidic (OoC) chip was placed on top of the cut-out window in the box Fig. (4b). The 37 mm tall platform box fits on the stage stably, with the weight of the components evenly distributed. It was possible to manually move the x-y stage and focus inside the microfluidic channels with 5x, 10x, 20x, and 40x objectives
