Abstract
Methods are disclosed for the simple, rapid, and selective colorimetric detection of carbohydrates, including fructose, glucose, sialic acid, and oligosaccharides. There is no need for any prior hydrolysis or other chemical modification or of the analytes. Resorcinarenes, xanthene dyes, and related compounds, formally produced by the reaction of 2 equivalents of resorcinol and a suitable electrophilic condensation partner, are used as chromophores or fluorophores for the detection of sugars and other carbohydrates.
