Researchers in the UK and Japan use atomic force microscopy to visualize a DNA molecular robot moving along a 100-nm DNA track.
A shear flow processing method has been developed to control the surface attachment and orientation of DNA molecules to use for DNA-organic semiconductor molecular building blocks.
A step toward advanced nanotechnology has been achieved by using attachment to a surface and confinement by surrounding molecules to make two molecules react to form a product that would not form if they were free to react in solution.
Computational work links optically-induced molecular shape change to change in DNA structure to extract useful work.
Sputtering a pattern of zinc atoms on a graphene surface, followed by an acid rinse to remove the zinc, also removes exactly one atomic layer of graphene from where ever the graphene was covered with zinc atoms, forming a pattern on the graphene surface that is atomically precise in the vertical dimension. Resolution in the horizontal dimensions is determined by the mask used to sputter zinc.
A French and Chinese collaboration has designed a molecular piston that self-assembles to form a complex stable enough that disassembly is very slow compared to the sliding motion of the piston.
Chinese scientists demonstrate that protein folding is a quantum transition between torsion states on a polypeptide chain.
Does nanotechnology need more energetic PR, and if so, what kind?
In yet another in a long list of improvements to DNA based molecular machines, DNA molecular robots learn to walk in any direction along a branched track.
James C. Ellenbogen writes to provide insight and personal perspective on the world’s first programmable nanoprocessor, achieved as the product of a collaboration between Harvard and MITRE, with the team at MITRE comprising Shamik Das, James Klemic, and Ellenbogen.
