A colorimetric sensing system based on gold nanoparticles functionalized with a water-soluble anion-recognition motif, an o-(carboxamido)trifluoroacetophenone analogue, has been developed. The nanoparticle system selectively senses specific isomers of dicarboxylates that are geometrically favorable for the binding-induced aggregation process; thus, it… CONTINUE READING
