Researchers have developed a novel method for creating self-assembled protein/polymer nanostructures that are reminiscent of fibers found in living cells. The work offers a promising new way to fabricate materials for drug delivery and tissue engineering applications.
Chemists have described the self-assembly of large, symmetrical molecules in bricks-and-mortar fashion, a development with potential value for the field of organic electronic devices such as field-effect transistors and photovoltaic cells.
Long before humans figured out how to create colors, nature had already perfected the process - think stunning, bright butterfly wings of many different hues, for example. Now scientists are tapping into those secrets to develop a more environmentally friendly way to make colored plastics.
A professor from Wayne State University's College of Engineering recently received a $330,000 award from the National Science Foundation for the project, 'Nanoparticle-directed synthesis of organic nanorods'.
The NNCO is now accepting questions related to the 'Progress Review on the Coordinated Implementation of the National Nanotechnology Initiative (NNI) 2011 Environmental, Health, and Safety Research Strategy'.
In addition to biodegradability and the ability to be recovered and re-used, cellulose nanoparticles are light and cheap, and they have very desirable mechanical properties. Therefore, they have high potential to be used in pharmaceutics, foodstuff, cosmetics, paper production and composite manufacturing.
The use of new nanomaterials in tyre production could help foster the sustainability of the tyre industry and reduce the environmental impact of vehicles, if the potential environmental, health and safety risks of the technology are managed carefully, according to the new OECD report 'Nanotechnology and Tyres: Greening Industry and Transport'.
