title: Highly selective ensembles for D-fructose based on fluorescent method in aqueous solution.
abstract: Three highly sensitive and selective switches for monosaccharides were composed by anionic polyelectrolyte PPPSO(3)Na and cationic viologen quencheres BBVs. The sensing processes of three ensembles (PPPSO(3)Na/o-BBV, PPPSO(3)Na/m-BBV and PPPSO(3)Na/p-BBV) to common seven monosaccharides have been determined by fluorescence spectra at pH 7.4 buffer solution. The results show that the three sensing ensembles all embody higher selectivity and sensitivity for d-fructose with reversible "on-off-on" fluorescence response. The research results can provide a new mode for developing highly selective probes.
