TL;DR: The method to image and reveal structural details of proteins on a truly single-molecule level is reported, using low-energy electron holography to image individual proteins electrospray deposited on freestanding graphene.

TL;DR: This work demonstrates the sequence-controlled fabrication of molecular nanostructures using peptides as bio-organic building blocks for two-dimensional (2D) self-assembly on surfaces and grants insight at the atomic level that will enable the use of oligo- and polypeptides as large, multi-functional bio- organic building blocks, and opens a new route towards rationally designed, bio-inspired surfaces.

TL;DR: Direct imaging of single glycan molecules that are isolated by mass-selective, soft-landing electrospray ion beam deposition and low-temperature scanning tunnelling microscopy resolves the structures of glycans at sub-nanometre resolution, revealing the connectivity of glycan chains and the types of linkages.

TL;DR: Excellent stability of a self-assembled ionic network on a metal surface at elevated temperatures is demonstrated and comparable strength of intermolecular ionic bonds and intramolecular covalent bonds has been achieved in this surface system.

TL;DR: The demonstrated 2D-folding scheme resembles many key properties of its native 3D counterpart and shows that functional, molecular nanostructures on surfaces fabricated by folding could be just as versatile and specific.
