TL;DR: This work revisits well-known microfluidic devices for hydrodynamic focusing, sized-based extraction of molecules from complex mixtures, micromixing, and dilution, and demonstrates that paper-based devices can replace their expensive conventional micro fluidic counterparts.

TL;DR: The system gave a detection limit in the sub-nanomolar range in under nine minutes, showing the potential to expand into quantitative, multi-analyte analysis of human blood samples, and selection of dry storage conditions, characterization of reagent rehydration, and execution of an automated on-card assay.

TL;DR: A platform that detects disease-specific antigens and IgM antibodies for sample-to-result differential diagnosis of infections that present with high rapid-onset fever is described and its strengths and weaknesses are detailed.

TL;DR: A mobile application that automatically quantifies immunoassay test data on a smart phone is presented and the speed and accuracy demonstrated suggest that cell-phone based analysis could aid disease diagnosis at the point of care.

TL;DR: In this paper, the authors exploit hydrodynamic addressing to provide simultaneous performance of multiple molecular affinity assays in parallel using a minimal sample volume flowing through a single channel, and demonstrate that the approach can be used to perform multiple assays at the same time.
