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 ...
