A trimeric protein was designed to self assemble into a 60 unit icosahedron with a roomy interior that might find use to ferry molecular cargo into cells or as a chemical reactor.

Recent research documents a structure-based rational design strategy combining molecular dynamics and single molecule imaging to improve the performance of a DNA tweezers that accurately positions an enzyme and its cofactor.
Left panel shows tweezers in the open position, with the enzyme (green) on the upper arm and the co-factor (gold) on the lower arm. Supplying a complementary fuel strand causes the tweezers to close, producing the reaction of the enzyme-cofactor pair. (Right panel) while a set strand restores ...

Combining computational nanotechnology with a noncontact-atomic force microscope probe tipped by a single CO molecule allowed researchers to visualize the dance of individual chemical bonds during a complex organic reaction on a silver surface.
Identification of reactants, transient intermediates, and products in a bimolecular enediyne coupling and cyclization cascade on a silver surface by non-contact atomic force microscopy. The corresponding chemical structures are depicted below the nc-AFM images. Image credit: A. Riss, ...

Removing the necessity of providing several different chemical fuels in a series of distinct steps, a novel chemically-fueled molecular motor autonomously produces movement as long as the fuel supply lasts.

Chains of monomers joined by non-biological peptoid bonds follow different rules of self-assembly and form structures not found in chains joined by the peptide bonds used to form proteins.
Snakes on a plane: This atomic-resolution simulation of a peptoid nanosheet reveals a snake-like structure never seen before. The nanosheet's layers include a water-repelling core (yellow), peptoid backbones (white), and charged sidechains (magenta and cyan). The right corner of the nanosheet's ...

The claim that the recently reported actuating nanotransducers (ANTS) produce forces "orders of magnitude larger than any produced previously" is challenged by a nanocrystal carbon nanotube device reported 11 years ago.

Computational design of an enzyme that carboligates three one-carbon molecules to form one three-carbon molecule, an activity that does not exist in nature, provides proof-of-principle for a novel metabolic pathway for carbon fixation.
