We have developed a compact disc (CD)-shaped microfluidic device for multiple, rapid enzyme-linked immunosorbent assays (ELISA). The device has a versatile design that can be adapted for the detection of various proteins by selecting the push-in-type reaction parts and appropriate reagents for each target. In this paper, we report the rapid quantification of insulin, adiponectin, and leptin, which can be used for the early diagnosis of diabetes, in human serum in only 16 min with our device.
