NIST's stretching exercises shed new light on nanotubes
...antly by wrapping SWNTs with DNA to keep them from clumping together, and dispersing them in a polymer. When they heated the polymer and stretched it in one direction, the nanotubes aligned like sugar crystals lining up in pulled taffy, making the optical measurements possible.

The nanoparticles are trapped inside the silicone device, which is sealed off by a porous membrane. The membrane allows molecules smaller than 30 nm to get in, but the detection particles are too...Alzheimer's alarm over anesthetics

A signal from inside the platelet to the outside tells the GPIIb-IIIa integrin on the cell's surface to get sticky.

...t with water. It also keeps the nanoparticles from clumping and behaving erratically. "The M&M analogy is really a great one because it says you can put things on the outside and you can have something on the inside," Watkin said.

... E2 (PGE2). These substances help prevent platelet clumping in blood vessels and vessel relaxation and/or constriction, respectively. Therefore, the challenge has been to identify a mechanism whereby PGI2 and PGE2 expression can be suppressed while avoiding adverse cardiovascular events.
