Triple helices stabilize macroscopic crystals for DNA nanotechnology

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.

Macroscopic DNA crystals from molecular tensegrity triangles

Structural DNA nanotechnology: progress toward a precise self-assembling three dimensional scaffold by building macroscopic crystals from nanoscale structures.

Five ionized atoms provide scalable implementation of quantum computation algorithm

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.

Tightly-fitted DNA parts form dynamic nanomachine

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.

Multiple advances in de novo protein design and prediction

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.

Rational design of protein architectures not found in nature

Computational design of proteins satisfying predetermined geometric constraints produced stable proteins with the designed structure that are not found in nature.

De novo protein design space extends far beyond biology

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.

DNA nanotechnology controls which molecules enter cells

DNA building blocks mimic biological ion channels to more precisely control which molecules can cross a biological membrane.

Molecular arm grabs, transports, releases molecular cargo

A molecular robotic arm synthesized from small synthetic organic molecules uses cyclic changes in pH and other reaction conditions to grab and release a cargo molecule, and swing the cargo back and forth between the two ends of the molecular platform.

Using DNA nanotechnology to position molecules with atomic precision

German researchers have used scaffolded DNA origami to adjust the angle of a DNA hinge joint by altering the length of special “adjuster helices”, causing molecules attached to the sides of the hinge to be displaced by as little as 0.04 nm.
