A high-resolution crystal structure of a small square made by self-assembly of RNA molecules reveals each corner of the square to have a unique structure.
Engineering both the pore size and chemical functionality of nanoporous materials affects both the secondary structure and the catalytic activity of the enzymes confined in the nanopores.
UK scientists use mechanical force to manipulate silicon dimers on a silicon surface as a first step toward automated atomically precise manufacture of three-dimensional nanostructures.
Researchers in the UK and Japan use atomic force microscopy to visualize a DNA molecular robot moving along a 100-nm DNA track.
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.
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.
Chinese scientists demonstrate that protein folding is a quantum transition between torsion states on a polypeptide chain.
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.
A new technique is reported to use templates to build synthetic molecules the size of proteins by precisely stringing together smaller molecules using an approach based upon the vernier scale.
