Abstract
A colorimetric sensing system of gold nanoparticles functionalized with carboxylate-binding units of o-(trifluoroacetyl)carboxanilide is described, which selectively recognizes a trans-dicarboxylate (fumarate) from its cis-isomer (maleate) and several dicarboxylates through inter-particle cross-linking, resulting in an apparent color change from red to purple.
Graphical abstractGold nanoparticles functionalized with o-(trifluoroacetyl)carboxanilides selectively sense a trans-dicarboxylate (fumarate) from its cis-isomer (maleate) and several dicarboxylates depending on substrate concentrations through inter-particle cross-linking, resulting in an apparent color change from red to purple.Download full-size image
