NanoSafe presentation will provide a 2007 update on the practical five-point risk management approach developed with industry, academia, and the National Institute for Occupational Safety and Health (NIOSH).
In an important step toward realizing the potential of radionuclide-loaded nanoparticles as radiotherapeutic agents, scientists have demonstrated that ultrashort carbon nanotubes will permanently entrap the potent alpha particle emitting element astatine-211, which has a half-life of 7.2 hours.
A new targeted drug delivery method, which combines two nanoparticles into one larger one, uses ultrasound to image tumors and release the anticancer drug doxorubicin from "nanobubbles" into the same tumors.
Take a quantum dot, add a coating of poly(ethylene glycol) (PEG), and attach a homing peptide and a piece of small interfering RNA (siRNA), and the result is a targeted nanoparticle that can stop the production of a specific protein by a targeted cell.
Build a pendulum small enough, and it will violate Newton's classical laws of mechanics, following quantum rules instead. Some researchers hope to observe such violations by cooling a tiny wobbling object to very low temperatures.
Researchers in Australia have developed a "switchable" detergent with a wide range of potential applications - from a laundry detergent that hardly needs a rinse cycle to a non-irritating eye rinse to increasing the amount of oil that companies can extract from a well.
Chemists have developed a method to dramatically improve the longevity of fluorescent nanoparticles that may someday help researchers track the motion of a single molecule as it travels through a living cell.
Researchers have found a simple, inexpensive way to create a nanowire coating on the surface of biocompatible titanium that can be used to create more effective surfaces for hip replacement, dental reconstruction and vascular stenting.
