Most chemical reactions perform best when shaken or stirred. Active mixing maximizes the chances that reactant molecules will find one another. But chemists who are exploiting small-volume reactions ...

The high cost of medical diagnostics and the importance of detecting infectious diseases in a timely, cost-effective manner have increased the importance of point-of-care (POC) testing. Lateral flow ...

A test for E. coli bacteria involving sheets of paper patterned by laser may assist doctors in developing countries and low-resource environments to identify infections more rapidly. Developed by the ...

Scientists used a 3D-printing approach to pattern hydrophobic barriers inside hydrophilic filter paper. These barriers, designed in different geometries, guide liquids along precise paths and shape ...
