Various types of carbon-based nanomaterials, such as buckyballs and nanotubes, have shown promise as drug delivery tools and imaging agents, but reports of toxicity associated with some of these materials have raised questions about their ultimate utility in clinical oncology. Three recent reports in the literature provide new insights into why certain carbon-based nanomaterials are toxic to cells and others are not.
A research team at Carnegie Mellon University has discovered a nanocrystalline material that is cheaper, more stable and produces a higher quality energy storage capacity for use in a variety of industrial and portable consumer electronic products.
Implants are prone to infection, forcing patients back to surgery for repair or replacement. Now, for the first time, a team of engineers has shown that zinc or titanium oxide nanosurfaces can reduce the presence of bacteria, a technique that can be applied to implants to reduce the number of these costly and debilitating infections.
NIST and the University of Maryland have joined in a cooperative program to develop measurement technology and other new tools designed to support all phases of nanotechnology development, from discovery to manufacture.
Researchers at Purdue University are using a rare type of electron microscope to see how structures like carbon nanotubes form at the atomic level, information that will be crucial for nanotechnology to find practical applications in computing, electronics and other areas.
