Sorting carbon nanotubes for different nanotechnology applications

An international team of scientists has shown that semiconductor nanotubes can be attracted to and aligned on surfaces chemically modified with amino groups, while surfaces with phenyl groups attract metallic nanotubes.

Nanotechnology may be able to deliver drugs across the blood-brain barrier

Researchers expect protein-conjugated quantum rods to be able to transport multiple agents across the blood-brain barrier so that they could function synergistically.

Nanotechnology provides key capability for artificial photosynthesis

Chinese scientists have developed a nanotech solution to harvest energy from multiple electrons—something alternative approaches to artificial photosynthesis have not yet managed to do.

Open source nanotechnology for clean water

From the conference report Setting an Agenda for the Social Studies of Nanotechnology (PDF): For example, researchers at Rice University have been working on the use of nanoparticles to absorb arsenic from drinking water supplies. Nanoscale iron oxide absorbs arsenic effi ciently, but in many countries implementing the process is either too expensive or technically… Continue reading Open source nanotechnology for clean water

Another way to manipulate individual DNA molecules

Individual DNA molecules can also be manipulated by optical tweezers and microfabricated structures.

Atomically precise nanotechnology leading to new catalysts

The emerging ability to control the sizes of these clusters to atomic precision affords new opportunities for designing novel catalysts.

Nanotechnology therapies for cancer progress, block metastasis

In experiments in mice, chemotherapy drugs encapsulated in nanoparticles targeted to the blood vessels that supply nutrients to tumor cells prevented the usually fatal spread of the cancer to additional sites.

Nanotechnology may allow hip implants to sense growth of new bone

The nanotech-prepared titanium surface serves as a sensor to detect bone formation.

Artificial DNA base pairs for nanotechnology building blocks

An ‘artificial DNA’ in which the two natural DNA base pairs have been replaced by two non-natural base pairs may provide useful new nanotech building blocks.

Nanotechnology may decrease energy costs for desalination

Scientists have continued progress toward the goal of nanotech membranes for water purification that will greatly decrease the energy cost for desalination.
