In Nanotechnology, copolymers play a crucial role due to their ability to self-assemble into nanoscale structures. This self-assembly is driven by the chemical incompatibility between different blocks of the copolymer, leading to the formation of well-defined nanostructures like micelles, vesicles, and nanoparticles. These structures are essential in various applications including drug delivery, nanofabrication, and material science.
