A 10-fold larger breadboard and 350-fold lower DNA synthesis costs make DNA origami a more useful stepping-stone toward atomically precise manufacturing.
In two different sets of experiments a German research group has shown that scaffolded DNA origami can be used to assemble complex structures with precise sub-nanometer positional control, and that constant temperature reaction can greatly increase yields and decrease production times.
Ultrafast molecular machines made using DNA nanotechnology have now been demonstrated. Over the past several years molecular machines made using DNA nanotechnology, especially the scaffolded DNA origami technology, have grown more complex and more functional (see, for example, here, here, here, and here). Long-time Foresight member Dr. Robert P. Meagley writes to point out that… Continue reading Ultrafast DNA robotic arm: A step toward a nanofactory?
Structural DNA nanotechnology: progress toward a precise self-assembling three dimensional scaffold by building macroscopic crystals from nanoscale structures.
Small, stiff, rectangular rods made using scaffolded DNA origami bypass drug resistance mechanisms in the membranes of a cultured leukemia cell line and release enough therapeutic drug to kill the cancer cell.
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.
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.
A lipid bilayer supported by a mica surface assisted the mobile self-assembly of DNA nanostructures of various shapes into micrometer-scale 2D lattices.
A new set of design rules enables constructing any wireframe nanostructure, which may lead to new medical applications and new nanomachines.
