Through the convergence of nano- and microtechnologies (quantum dots and microfluidics), we have created a diagnostic system capable of multiplexed, high-throughput analysis of infectious agents in human serum samples. We demonstrate, as a proof-of-concept, the ability to detect serum biomarkers of the most globally prevalent blood-borne infectious diseases (i.e., hepatitis B, hepatitis C, and HIV) with low sample volume (<100 μL), rapidity (<1 h), and 50 times greater sensitivity than that of currently available FDA-approved methods. We further show precision for detecting multiple biomarkers simultaneously in serum with minimal cross-reactivity. This device could be further developed into a portable handheld point-of-care diagnostic system, which would represent a major advance in detecting, monitoring, treating, and preventing infectious disease spread in the developed and developing worlds.
