Calculations using density functional theory have demonstrated that graphene can be made piezoelectric by adsorbing atoms or molecules on one surface, or by adsorbing different atoms or molecules on each surface.
Creating a superlattice by placing graphene on boron nitride may allow control of electron motion in graphene and make graphene electronics practical.
A set of rationally engineered transcriptional regulators for yeast will make it easier to build complex molecular machine systems in yeast, some of which may become useful additions to pathway technologies for atomically precise manufacturing and productive nanosystems.
A combination of a molecular motor protein and a nanopore protein has been harnessed for rapidly sequencing single DNA molecules.
Functioning DNA nanorobots to deliver specific molecular signals to cells were designed by combining DNA origami, DNA aptamers, and DNA logic gates.
A talk at TEDxBerkeley includes nanotechnology among the options for digital fabrication, one of five new rules of innovation.
New computational methods to explore the rapidly expanding collection of high resolution three-dimensional RNA structures reveal new RNA structural motifs, identifying additional building blocks for complex RNA nanostructures.
A set of machine learning programs can now predict properties of small organic molecules as accurately as can calculations based upon the Schrödinger equation, but in milliseconds rather than hours.
Researchers in Australia and the US have demonstrated a working transistor by placing of single atom of phosphorous with atomic precision between gates made of wires only a few phosphorous atoms wide. This demonstration points to possibly extending current computer technology to the atomic scale.
A field-effect tunneling transistor comprising a vertical heterostructure of atomically thin layers of graphene and boron nitride or molybdenum disulfide may pave the way for computer chips based on graphene nanotechnology.
Scientists at Kyoto University and the University of Oxford have combined DNA origami and DNA motors to take another step toward programmed artificial molecular assembly lines.
Foldit game players have again out-performed scientists in protein design, this time improving the design of a protein designed from scratch to catalyze Diels-Alder cycloadditions.
Human life after advanced nanotechnology has been developed will be fundamentally different from life up until that point.
An array of 96 iron atoms on a copper nitride surface, assembled using an STM and used to write a byte, demonstrates how small magnetic storage could shrink and may lead to novel nanomaterials for quantum computers.
An article in The Guardian quotes Christine Peterson and Robert Freitas on the vision of molecular manufacturing. Freitas is quoted as expecting that the development of nanofactories could be done in 20 years for “on the order of” one billion dollars.
A four-step unidirectional molecular motor driven by light and temperature changes catalyzes different chemical reactions at different steps of its rotary cycle.
