Nanotweezers unlock anticancer drug secrets

The annoying bulges of an overwound telephone cord that shorten its reach and limit a caller's motion help explain why drugs called camptothecins are so effective in killing cancer cells.

Metal nanoshells respond to near-infrared light for tumor imaging and therapy

Using metal nanoshells designed to both absorb and scatter near-infrared light, a team of investigators has shown that such nanoparticles can both image and treat tumors in animals.

Nanotubes enable new approach to cancer radiotherapy

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.

Multifunctional nanoparticles combine ultrasound imaging and targeted anticancer therapy

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.

Targeting quantum dots to deliver SiRNA therapy

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.

Watching an object go quantum

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.

Using DNA to control nanoparticle assembly

Using DNA, the molecule that carries life's genetic instructions, researchers are studying how to control both the speed of nanoparticle assembly and the structure of its resulting nanoclusters.

Detergents, eye rinses and other products with an on/off switch

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.
