The expanding role of paper in point-of-care diagnostics

摘要

This editorial discusses the expanding role of paper as a platform on which to build new point-of-care assays, particularly those intended for use in resource-limited settings. Successful diagnostics for use in these environments require a low-cost platform (possibly paper) as well as new assay strategies, reagents and materials for achieving selectivity and sensitivity. Paper provides a common platform for bringing these components together and serves as a low-cost medium for prototyping new point-of-care assays.
