 Amphiphilic block copolymers can, in selective solvents such as water, assemble into various shapes and architectures. Among those, polymer vesicles, polymer micelles and polymer fibers are very popular structures in current nanotechnology. These objects each have their own particular properties and can serve as containers or templates for different nanotechnological applications. Polymer vesicles, for example, can encapsulate both hydrophobic and hydrophilic molecules, and are therefore considered as attractive candidates for drug delivery, nanoreactors and also microtemplates. Polymeric micelles are usually significantly smaller. Their hydrophobic cores are typically used to solubilize hydrophobic drugs or carry biomolecules. Polymer fibers by construction are long continuous entities. Because of this, they easily form gels at relatively low concentrations and may find functions as templates/substrates in biological applications. In some cases the can carry or conduct charges which may trigger their use in electronic devices. This dissertation studies the function and application of polymer vesicles, polymer micelles and polymer fiber.
