An integrated centrifugal microfluidic platform for multiplexed colorimetric immunodetection of protein biomarkers in resource-limited settings

• The up- and down- regulation of inflammatory biomarkers such as cytokines can be indicative of several diseases such as primary cancers and/or metastatic tumors, as well as less serious conditions. For point-of-care clinical applications, the detection of these biomarkers requires a combination of a sensitive assay and multiplexing capabilities, together with fit-for-purpose signal transduction strategies. Here, we report the development of a versatile and cost-effective integrated centrifugal microfluidic platform compatible with resource-limited settings using nanoporous microbeads for immunoaffinity-based profiling of cytokines. With an automated colorimetric readout at the end, the platform allows for profiling of cytokines in < 30 mins.
