摘要: Abstract The present work represents new facile route for synthesis of luminescent hydrophilic core-shell colloids, where the luminescence results from Au(I) complex (AuCl)2L with cyclic PNNP ligand (L). is based on solvent mediated aggregation in aqueous organic solutions. Instability solutions was minimized by specific shell deposition arisen electrostatically driven adsorption polyethylenimine onto (AuCl)2L-based cores. Luminescence colloids stable week at least due to restricted degradation interface and high positive exterior charge colloids. sensing properties towards thiols their formation Au+ ions. thiol-induced stripping ions quenches luminescence. optimal conditions fluorescent recognition cysteine, homocysteine glutathione lower detection limits about 1 μM are highlighted work.
