Abstract
Novel beta-cyclodextrin-4,4'-dipyridine supramolecular inclusion complex-modified silver nanoparticles were synthesized for the colorimetric determination of Yb(3+) ions in aqueous solution with high sensitivity (the visual detection limit was 2 x 10(-7) M), via Yb(3+)-induced aggregation to form chain-like supramolecular aggregates.
