Two-dimensional (2D) materials have unique physical and chemical properties and potential for a wide variety of applications. Peptoids, a type of molecule, compose a class of sequence-defined polymers that mimic biological compounds and can self-assemble into 2D crystalline sheets with unusual properties, such as high chemical stability and the ability to repair themselves.
