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.
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.
A DNA strand capable of forming a triple helix with a portion of the DNA double helices in a macroscopic DNA crystal enhances the weak interactions holding the crystal together so that the crystal remains stable in the absence of a high ionic strength environment.
Five calcium ions held several micrometers apart in an ion trap and manipulated by laser pulses implement Shor’s factorization algorithm more efficiently than previous implementations.
A rotor with DNA origami parts held together by an engineered tight fit instead of by covalent bonds can revolve freely, driven by Brownian motion and dwelling at engineered docking sites.
New families of protein structures, barrel proteins for positioning small molecules, self-assembling protein arrays, and precision sculpting of protein architectures highlight de novo protein design advances.
Computational design of proteins satisfying predetermined geometric constraints produced stable proteins with the designed structure that are not found in nature.
A fully automated design protocol generates dozens of designs for proteins based on helix-loop-helix-loop repeat units that are very stable, have crystal structures that match the design, have very different overall shapes, and are unrelated to any natural protein.
The ability to dope graphene nanoribbons with boron atoms to atomic precision opens a range of possible new applications, from chemical sensing to nanoelectronics to photocatalysis to battery electrodes.
