Nanotechnology combines an enzyme and a DNA molecule on the surface of gold nanoparticles to destroy hepatitis C virus in human cells and in a mouse model of disease.
A forest of long DNA strands hanging at known positions from a thin gold foil may provide a method to detect hypothetical particles of dark matter, thought to compose 26% of the universe.
A new nanomaterial provides a three million-fold improvement in the sensitivity of common medical tests, potentially permitting earlier detection of cancer and Alzheimer’s disease.
Current methods can image individual atoms in complex structures if the structures are crystalline, comprising many identical structures in a regular array. A new method resolves individual atoms in nanoparticles comprising several irregularly arranged crystalline grains.
Zyvex Technologies and ENVE Composites have demonstrated the superiority of a proprietary nanostructured composite in downhill cycling.
Templates made from polymer nanofibers enable the formation of long-lived silicon nanostructures that store ten times as much charge as do graphite battery terminals.
Nanoparticles targeted to cancer cells by antibodies cannot achieve enough specificity to kill drug-resistant cancer cells while sparing normal cells, but can achieve enough specificity to produce nanobubbles only in cancer cells, so the drug only enters cancer cells.
Doping carbon nanotubes with boron while they are being formed produces a novel molecular architecture formed by boron induced kinks and linkages. These nanosponges can be used repeatedly to absorb and retrieve or burn spilled oil.
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.
Gold nanostars targeted to a protein over-expressed in most cancer cells are shuttled by that protein directly to the cancer cell nucleus where illumination with a laser light releases a drug that deforms the nucleus and kills the cell.
Clinical trials in patients with advanced or metastatic tumors using targeted nanoparticles to deliver a standard chemotherapeutic drug showed tumor shrinkage, even in the case of cancers for which that drug is not normally effective.
A new two-photon polymerization process enables fast printing of arbitrarily complex three dimensional objects with 100-nanometer resolution.
A hand-sized adhesive inspired by the skin and tendon morphology of a gecko provides an easily reversible force capable of holding 700 pounds on a glass surface.
In a rat model of ischemic damage, nanoparticle delivery of a growth factor and a coreceptor promotes regrowth of damaged blood vessels in seven days.
New protein repellent coating enhances the speed of carbon nanotube-based biosensors, pointing the way to faster, cheaper medical diagnostics.
Composites made with small amounts of multi-walled carbon nanotubes improve wind turbine blades by reducing mass while retaining strength.
Artist’s conception of a nanopore drilled into a layer of graphene to speed up DNA sequencing. One of the greatest promises of near-term nanotechnoloogy is cheaper DNA sequencing to speed the development of personalized medicine. There are not only genetic differences between different patients, but also genetic differences between, for example, different cancers of the [...]
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.
