Laser-patterned lateral-flow devices with multiple flow-paths for semi-quantitative measurement of the inflammatory biomarker, C-reactive protein (Conference Presentation)

Paper Abstract

We report a novel solution for semi-quantitative detection of C-reactive protein (CRP), a common inflammatory marker, using a multi-path lateral-flow device (LFD) fabricated via the precise partitioning of the single flow-path of a standard LFD using a laser direct-write technique. The multiple isolated flow-paths allow detection of different concentrations by individually setting different cut-off levels. The semi-quantitative readout is observed via simple appearance/absence of test lines without the need for a reader or further analyses. We have successfully demonstrated the use of these multi-path LFDs for semi-quantitative detection of CRP and will present validation in human samples.
