Bacteria use Batman-like grappling hooks to 'slingshot' on surfaces

Bacteria use various appendages to move across surfaces prior to forming multicellular bacterial biofilms. Some species display a particularly jerky form of movement known as "twitching" motility, which is made possible by hairlike structures on their surface called type IV pili, or TFP.

Injections or sampling? New nanotechnology syringes under testing

The easiest and most natural way of penetrating a cell membrane with a carbon nanotube, in its simplest form, is at an angle which is almost flat against the membrane surface, according to a team of Italian researchers. Just as a nurse does to find a vein.

Heated AFM tip allows direct fabrication of ferroelectric nanostructures on plastic

Using a technique known as thermochemical nanolithography (TCNL), researchers have developed a new way to fabricate nanometer-scale ferroelectric structures directly on flexible plastic substrates that would be unable to withstand the processing temperatures normally required to create such nanostructures.

Nanoparticles working in harmony

A team of researchers from MIT, the Sanford-Burnham Medical Research Institute, and the University of California at San Diego (UCSD) has designed a new type of delivery system in which a first wave of nanoparticles hones in on the tumor, then calls in a much larger second wave that dispenses the cancer drug. This communication between nanoparticles, enabled by the body's own biochemistry, boosted drug delivery to tumors by more than 40-fold in a mouse study.

Polymeric nanoparticles attack head and neck cancer

Head and neck cancer, the sixth most common cancer in the world, has remained one of the more difficult malignancies to treat, and even when treatment is successful, patients suffer severely from the available therapies. Now, researchers at the University of Michigan have developed a tumor-targeted nanoparticle that delivers high doses of anticancer agents directly to head and neck tumors.

Nanoparticles disguised as red blood cells deliver cancer-fighting drugs

Researchers at the University of California, San Diego have developed a novel method of disguising nanoparticles as red blood cells, enabling the resulting nanoparticles to evade the body's immune system and deliver cancer-fighting drugs straight to a tumor.
