Nanoporous pigments laid out in a grid can help researchers identify 14 different sugar and artificial sweetener products, according to Christopher J. Musto, Sung H. Lim, and Kenneth S. Suslick, of the University of Illinois, Urbana-Champaign, who created the disposable colorimetric sensor device (Anal. Chem., DOI: 10.1021/ac901019g). Each sensor contains one of 16 indicator molecules trapped in a nanostructured organically modified silane . . .
