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.
ideo of a superhydrophobic spray-on coating shows chocolate syrup shooting off a white shoe leaving it spotless.
A National Academy of Sciences panel has recommended a four-part research effort focused on preventing and managing any potential health and environmental risks of nanomaterials.
The first Master’s of Science in Nanomedicine degree program in US is announced. As an example of the rapidly developing potential of nanomedicine, a novel type of nanoparticle succeeded in two different mouse models in destroying a type of brain cancer that had previously been completely resistant to all treatment attempts.
Protein-like structures called peptoids can be formed into stable, free-floating nanosheets.
When can we expect advanced nanomachinery to be commercialized? Will any technologies not be affected in some way by advanced nanotechnology?
Controlling the chemical processes of corrosion and plating at the nanoscale has been used to fabricate from inorganic nanoparticles complex three-dimensional objects with hollow interiors.
In a lecture at Oxford Eric Drexler argued that atomically precise manufacturing will be the next great revolution in the material basis of civilization, and discussed how we can establish reliable knowledge about key aspects of such technologies.
A new polymer that disintegrates in response to harmless radiation that can penetrate several inches into human tissue may lead to nanoparticles that release their drug cargo only at a desired time and place.
To counter the threat of evolved or engineered resistance of pathogenic bacteria to antibiotics, Darpa proposes to use nanotechnology to develop “Rapidly Adaptable Nanotherapeutics”.
