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 ...

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 ...

With bright packaging, tinsel tape, coloured string and ‘Don’t open me till Christmas morning!’ tags, “there is no possible ...
