How It Works (image) DOE/Lawrence Berkeley National Laboratory Share Print E-Mail Caption Long organic molecules called peptoids self-assemble into a molecular film on the surface of a water solution. As this film gets folded into a nanosheet, segments of the peptoid get pushed out into loops, which eventually decorate the surface of the nanosheet.
