Proposed structure of self-assembled nanoshells. The inner side of the spheres are coated with the hydrophobic ligand (DPA), facing encapsulated toluene, and the outer side is coated with the hydrophilic ligand (G6P), facing the water phase. The alginate polymer helps stabilizing the nanoshells and may interact with the hydrophilic ligand via hydrogen bonding, and potentially via electrostatic interaction with the titania surface.
