The immune response triggered by carbon nanotube-like structures could be harnessed to help treat infectious diseases and cancers, say researchers. The way tiny structures like nanotubes can trigger sometimes severe immune reactions has troubled researchers trying to use them as vehicles to deliver drugs inside the body in a targeted way. White ...

Researchers at North Carolina State University have discovered that adding tiny bits of gold to a failed HIV drug rekindle the drug's ability to stop the virus from invading the body's immune system. The researchers started with a modified version of TAK-779, which didn't include the harmful ammonium salt. After testing, they found ...

Early-stage tumors are often too small to see with magnetic resonance imaging (MRI). Now, a team of researchers has developed magnetic "nanoworm" particles that can circulate for a day in the bloodstream and home in on tumors, helping to enhance an MRI image. The nanoworms could make it easier to image small tumors, allowing ...

A startup based in Cambridge, MA, says that it plans to soon begin clinical trials of a nanostructured material that stops bleeding almost instantly. A startup called Arch Therapeutics has licensed the technology from MIT and is developing manufacturing processes for making it in large amounts. The new material can be poured over a site ...

A new technique in paint making could soon make almost any surface germfree. Researchers have made paint that is embedded with silver nanoparticles known for their ability to kill bacteria and other microbes, in the hope that hospitals will coat their walls and countertops to fight infection. According to the U.S. Centers for Disease Control ...

Bacterial nanoparticles without chromosomes have been created that can carry high-dose combinations of drugs to exactly where they are needed without releasing them into the general circulation....

A new electric propulsion concept proposes to utilize electrostatically charged and accelerated nanoparticles as propellant. Millions of micron-sized nanoparticle thrusters would fit on one square centimeter, allowing the fabrication of highly sc...

The world's first direct electrical link between nerve cells and photovoltaic nanoparticle films has been achieved by researchers at the University of Texas Medical Branch at Galveston and the University of Michigan. The development opens the doo...

From earlier this month, a Nanowerk article does into more detail on the proposed use of artificial cells and cell-like structures as medical devices: ''Some fundamental problems like the targeting of nanoparticles in vivo, the transport of unstable drugs, and the dosage control of drug-carrying nanoparticles lead some scientists to think even one ...
