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 H-1-NMR spectroscopy and quantitatively by isothermal titration calorimetry (ITC).
