Abstract
Nanostructure fabrication from block copolymers is discussed in this review paper. Particularly, novel approaches for the construction of functionalized poly(ethylene glycol) (PEG) layers on surfaces were focused to attain the specific adsorption of a target protein through PEG-conjugated ligands with a minimal non-specific adsorption of other proteins. Furthermore, surface organization of block copolymer micelles with cross-linking cores was described from the standpoint of preparation of a new functional surface-coating with a unique macromolecular architecture. The micelle-attached surface and the thin hydrogel layer made by layered micelles exhibited non-fouling properties and worked as a reservoir for hydrophobic reagents. These PEG-functionalized surface in brush form or in micelle form can be used in diverse fields of medicine and biology to construct high-performance medical devices including scaffolds for tissue engineering and matrices for drug delivery systems.
