Triple Complexes of Bismuth Nanoparticles with β-Cyclodextrin and Polyvinylpyrrolidone

摘要: Ternary complexes of bismuth nanoparticles with β-cyclodextrin and polyvinylpyrrolidone are studied via UV visible spectroscopy dynamic light scattering. It is shown that, depending on the ratio concentrations to in a synthetic medium, can be stabilized sterically either by distributing molecules over surface complex or forming inclusion hydrophobic cavity as result associated being pushed apart molecules. The conditions determined for formation ternary that aggregatively stable 20 days characterized unimodal particle size distribution.
