Functional nanoparticle based on β-cyclodextrin

Aminoethylcarbamoyl-β-cyclodextrin (AEC-β-CD)-based nanoparticle is prepared by an interfacial polyaddition reaction. The nanoparticle has high β-CD content and many amino groups on the surface. The β-CD cavity of this particle forms inclusion complexes with aromatic molecules, where the uptake ability significantly depends on physicochemical factors such as hydrophobicity, ionic charge, size, and shape of guest molecules.
