title: Point-of-care microdevices for blood plasma analysis in viral infectious diseases.
abstract: Each year, outbreaks of viral infections cause illness, disability, death, and economic loss. As learned from past incidents, the detrimental impact grows exponentially without effective quarantine. Therefore, rapid on-site detection and analysis are highly desired. In addition, for high-risk areas of viral contamination, close monitoring should be provided during the potential disease incubation period. As the epidemic progresses, a response protocol needs tobe rapidly implemented and the virus evolution fully tracked. For these scenarios, point-of-care microdevices can provide sensitive, accurate, rapid and low-cost analysis for a large population, especially in handling complex patient samples, such as blood, urine and saliva. Blood plasma can be considered as a mine of information containing sources and clues of biomarkers, including nucleic acids, immunoglobulin and other proteins, as well as pathogens for clinical diagnosis. However, blood plasma is also the most complicated body fluid. For targeted plasma biomarker detection or untargeted plasma biomarker discovery, the challenges can be as difficult as identifying a needle in a haystack. A useful platform must not only pursue single performance characteristics, but also excel at multiple performance parameters, such as speed, accuracy, sensitivity, selectivity, cost, portability, reliability, and user friendliness. Throughout the decades, tremendous progress has been made in point-of-care microdevices for viral infectious diseases. In this paper, we review fully integrated lab-on-chip systems for blood analysis of viral infectious disease.
