Nano-engineering biocompatible materials 2008-05-06 07:33:00 A research team from the University of Manchester aims to develop a 3D scaffold appropriate for surgical implantation into damaged tendons. Highly aligned fibres to encourage correct formation of new muscle tissue and formation of 3D aligned fibrous bundles for tendon regeneration by using electrospinning. They envisage that this synthetic structure will perform the mechanical functions of a tendon whilst promoting cell migration and subsequent repair. Depending on the success of this, further clinical trials are planned and it is anticipated that an "off-the-shelf" product will be available within five years.Source: nanotechweb.org ...

Feynman Prizes in Nanotechnology: Nominations due May 31 2008-05-05 23:18:00 The Foresight Institute Feynman Prizes, named in honor of pioneer physicist Richard Feynman, are given in two categories, one for experiment and the other for theory in nanotechnology. Established in 1993, the prizes honor researchers whose recent work has most advanced the achievement of Feynman's goal for nanotechnology: the construction of atomically-precise products through the use of productive nanosystems."The Feynman Prizes have recognized the most important nanoresearch work for over a decade. We invite the nanotech community to let us know who most deserves to join this group of brilliant achievers," said Christine Peterson, President of Foresight Nanotech Institute.Nominations for the Feynman Prizes may be made at: www.foresight.org/prizeSource: Foresight Nanotech Institute ...

Researchers produce 3-D nanotube circuits 2008-05-05 22:59:00 A team of researchers at the National Institute of Advanced Industrial Science and Technology in Tsukuba, Ibaraki Prefecture, has succeeded in producing hyperfine 3-D circuits using carbon nanotubes, it was learned Sunday. The team led by Kenji Hata released their findings in the on-line version of the May 4 issue of Nature Nanotechnology. The discovery is expected to help reduce the size of integrated circuits and allow the development of highly sophisticated sensors, the researchers said. The researchers synthesized nanotubes by blowing carbon gas that had been heated to about 800 C over a silicon board. They then processed the resulting nanotubes applying a technique normally used to make semiconductors. The process enabled the researchers to produce ultrafine wires as thin as 0.0001 millimeter, and 3-D structures. "Our approach opens up new ways to make economical and scalable devices with unprecedented structural complexity and functionality," they said in the article.Source: ...

International Council on Nanotechnology Launches Global Research Needs Assessment 2008-05-05 00:03:00 Last year, more than 70 experts from 13 countries - in academia, industry, governments and non-governmental agencies - accepted that challenge. In an unprecedented international collaboration, the International Council on Nanotechnology (ICON) convened two workshops aimed at defining a set of research needs for assessing potential nanotechnology impacts. The results of this multi-stakeholder effort, funded by ICON and the National Science Foundation, will be unveiled on Thursday, May 1, when ICON, in partnership with the Project on Emerging Nanotechnologies, releases the “International Assessment of Nanotechnology Environment, Health and Safety Research Needs” - a report on the findings of the two workshops.Source: Project on Emerging Nanotechnologies ...

Nano Scaffold Developed To Rebuild Nerve Damage 2008-05-03 02:15:00 A Monash University PhD student has developed a new technique that could revolutionise stem cell treatment for Parkinson's disease and spinal cord injury. David Nisbet from Monash University's Department of Materials Engineering has used existing polymer-based biodegradable fibres, 100 times smaller than a human hair, and re-engineered them to create a unique 3-D scaffold that could potentially allow stem cells to repair damaged nerves in the human body more quickly and effectively.Source: ScienceDaily, Feb. 2008 ...

Electrospun zein fibers using glutaraldehyde as the cross-linking reagent-effect of time and temperature 2008-05-03 00:56:00 With the fast-growing bio-ethanol industry, it is very important to use the co-products generated during ethanol production in a fashion that will improve the economics of this new industry. Zein, the dominant corn protein, is present in large amounts in the main co-products of both wet-milling and dry-milling ethanol plants. It is typically isolated from corn gluten meal (generated by ethanol producers using wet milling techniques). The main use of zein historically was in the textile fibers market.Ref: S.Gordon, W.Kristen, S.David, B.Atanu, Macromolecular Chemistry and Physics, 2008 ...

Electrospun nanofibers: solving global issues 2008-05-03 00:06:00 Nanofibers are able to form a highly porous mesh and their large surface-to-volume ratio improves performance for many applications. Electrospinning has the unique ability to produce nanofibers of different materials in various fibrous assemblies. The relatively high production rate and simplicity of the setup makes electrospinning highly attractive to both academia and industry. A variety of nanofibers can be made for applications in energy storage, healthcare, biotechnology, environmental engineering, and defense and security.Ref: Materials Today, Volume 9, Issue 3, March 2006, Pages 40-50 ...

Biomaterials for tendon repair 2008-05-02 21:18:00 Scientists at The University of Manchester, UK, are investigating the use of electrospun polycaprolactone nanofibres to regenerate damaged tendons. Because the bundle of fibres replicates the morphology of tendon tissue, researchers envisage that the synthetic structure will perform the mechanical function of the tendon while it repairs itself, as well as act as a temporary scaffold to promote cell migration and new tissue formation. Research will now focus on pre-clinical tests in the Achilles heal of a mouse, exploring control of biodegradation in terms of strength retention and mass loss.Source: Materials World ...

Electrospun memories 2008-05-02 08:54:00 Far from being simple conductors for transporting charge in future nanoelectronic devices, nanowires exhibit unique characteristics that could be also be exploited for other applications. An example of such multifunctional properties is provided by Wei Pan and colleagues at Tsinghua University in Beijing, China who find that aluminium-doped zinc oxide (AZO) nanowires exhibit both photoconductivity and voltage–induced bistable switching behaviour.Ref: Lin, D., Wu, H. & Pan, W.
