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.

Researchers expect protein-conjugated quantum rods to be able to transport multiple agents across the blood-brain barrier so that they could function synergistically.
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.
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
Individual DNA molecules can also be manipulated by optical tweezers and microfabricated structures.
The emerging ability to control the sizes of these clusters to atomic precision affords new opportunities for designing novel catalysts.
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.
The nanotech-prepared titanium surface serves as a sensor to detect bone formation.
An ‘artificial DNA’ in which the two natural DNA base pairs have been replaced by two non-natural base pairs may provide useful new nanotech building blocks.
Scientists have continued progress toward the goal of nanotech membranes for water purification that will greatly decrease the energy cost for desalination.
