New color chemosensors for monosaccharides based on Azo dyes

[GRAPHICS] Sugar detection is important for many applications. New developments in 7 s ugar signaling would provide new technologies to monitor glucose and other sugars. Azo dye 1 presents a new way to build molecular color sensors for m onosaccharides. The boronic acid group is used as chelator group for monosa ccharides and linked directly,in resonance with the aromatic dye. Dye 1 sho ws a color change, from orange to purple, in the presence of sugar at neutr al pH.
