G. Whitesides and his team at Harvard University have developed a prototype for an inexpensive, highly practical rapid test that can be used to carry out several biological tests simultaneously on a ...

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 ...

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 ...

This press release is also available in German. Testing biological fluids such as blood and urine is essential for both diagnostics and routine checks. In remote, non-industrialized regions or for ...

Paper is a hydrophilic material meaning that its affinity with water allows solutions to flow through the porous structure. This simple capillary action does not require added mechanical constructions ...
