DNA sequences designed to either stimulate a specific immune response or to down-regulate an undesirable response deliver superior performance when organized on nanoparticles to reach their intended cellular targets.
A prototype system to produce chemicals and fuels from sequestered carbon dioxide, water, and sunlight uses semiconductor nanowires to produce electron-hole pairs, which are then used by two types of bacteria to produce oxygen and a variety of useful chemical products.
A European Science and Technology Roadmap for Graphene, Related Two-Dimensional Crystals, and Hybrid Systems hints at the opportunities to be harvested from, and the need for, the development of atomically precise manufacturing (APM).
A new form of carbon produced by very slowly releasing benzene compressed at 200,000 times atmospheric pressure may be the strongest material possible.
Advanced aberration-corrected scanning transmission electron microscopes in UK facility provide atomically precise characterization of a variety of materials to guide R&D in alloys, drug delivery, lasers and other areas.
Gold nanotubes engineered to a specified length, modified surfaces, and to have other desirable characteristics showed expected abilities to enter tumor cells in laboratory studies, and to distribute to tissues within live mice as intended.
A nanoporous form of graphene made by burning off other elements from an inexpensive polymer has been used to fabricate flexible supercapacitors via a process that can be scaled to industrial quantities to provide energy storage for wearable, flexible electronics.
In tests in a mouse model of advanced atherosclerosis, core-shell nanoparticles, composed of block copolymers and targeted to sites of inflammation and vascular injury, delivered a bioactive peptide that improved key properties of advanced plaques.
Bulk nanoscale technologies were used to create three-segment nanowires of gold and nickel, and magnetic bearings of gold, nickel, and chromium. Combinations of DC and AC electric fields were used to assemble nanomotors that can spin at speeds up to 18,000r.p.m., and for up to 15 hours.
IBM researchers engineered a class of molecules called block copolymers to self-assemble into dense patterns to extend the capabilities of photolithography.
Mixing two different types of cylindrical nanoparticles causes them to reorganize into smaller spherical nanoparticles. A mechanism to release drugs only inside cells that internalize both types?
Computational simulations demonstrate that pentagonal tiling to give a variant of graphene based on pentagons rather than on hexagons is dynamically, thermally, and mechanically stable.
Applications of nanotechnology to wearable electronics and other portable devices will benefit from the discovery that adding an insulating layer to a piezoelectric nanostructure increases the output voltage by up to 200 times.
A simple method of producing nanoporous alumina surface discourages bacteria from attaching and forming biofilms, with potential applications in medicine, dentistry, and food processing.
Painting atomically precise carbon nanotubes onto a cathode produces flat panel lights a hundred times more energy efficient than LEDs.
The US National Science Foundation announced a new grant program to develop and apply next-generation networking to advance nanotechnology and other emerging technologies to meet important national needs.
A small, interactive group of invited experts gathered in Palo Alto recently to discuss prospects for revolutionary advances in energy storage, transmission, and generation through nanotechnology.
A nanoparticle that self-assembles from porphyrin, cholic acid, amino acids, and polyethylene glycol is a promising vehicle for delivering both imaging agents and cancer drugs to tumors.
