Abstract

Block copolymers composed of a hydrophilic and a hydrophobic segment self-assemble in water into nanoparticles with sizes and shapes that depend on the nature and length of each segment. Accordingly, it is possible to control the assembly process to generate various nanomaterials, such as spherical micelles, worm-like micelles, or vesicles. We developed a method to directly synthesize block copolymers inside the liquid cell of an electron microscope, providing unprecedented real-time insight into the progression and evolution of polymerization and self-assembly processes.
