There are several types of self-assembled structures, including: - Micelles: Spherical structures formed by the aggregation of amphiphilic molecules in aqueous solutions. - Liposomes: Vesicle-like structures composed of a lipid bilayer, useful in drug delivery. - Block copolymers: Polymers composed of two or more distinct blocks that can form various nanostructures. - Nanotubes: Cylindrical nanostructures with applications in electronics and materials science.
