摘要

Novel β-cyclodextrin–4,4′-dipyridine supramolecular inclusion complex-modified silver nanoparticles were synthesized for the colorimetric determination of Yb3+ ions in aqueous solution with high sensitivity (the visual detection limit was 2 × 10−7 M), viaYb3+-induced aggregation to form chain-like supramolecular aggregates.
