Unspecific ligand binding yielding stable colloidal ITO-nanoparticle dispersions.

Long-term stable ITO-nanoparticle dispersions are obtained using primary unbranched alkylamines with different chain lengths (C(3)-C(12)). The particles are stable despite weak interactions between the stabiliser and particle surface, which were qualitatively studied by (1)H-NMR spectroscopy and quantitatively by isothermal titration calorimetry (ITC).

Molecularly imprinted nanospheres by nonaqueous emulsion polymerization.

The preparation of nanosized, molecularly imprinted polymer particles by nonaqueous emulsion polymerization is presented. Monodisperse cross-linked polymer nanospheres with a diameter of around 100 nm were synthesized using a standard monomer mixture of methacrylic acid and ethylene dimethacrylate, containing (±)-propranolol as a template. The rebinding efficiency of the resulting particles was determined by batch rebinding tests and isothermal titration calorimetry (ITC).

Persistently folded circular aromatic amide pentamers containing modularly tunable cation-binding cavities with high ion selectivity.

In this work, we illustrated a novel design strategy that allows systematically tunable interior properties (effective cavity size, steric crowdedness, and hydrophobicity) contained within a novel class of shape-persistent aromatic pentamers to take place on a scale below 3 A. Such finely tunable structural features are complimented by experimentally observable functional variations in ion-binding potential. Results of the selective, differential binding affinities of three circular pentamers for Li(+), Na(+), K(+), Rb(+), and Cs(+), substantiated by metal-containing crystal structures and computational modeling, are detailed.
