UCLA physicists have made nanomechanical measurements of unprecedented resolution on protein molecules.

The new measurements, by UCLA physics professor Giovanni Zocchi and former UCLA physics graduate student Yong Wang, are approximately 100 times higher in resolution than previous mechanical measurements, a nanotechnology feat which reveals an isolated protein molecule, surprisingly, is neither a solid nor a liquid.

“Proteins are the molecular machines of life, the molecules we are made of,” Zocchi said. “We have found that sometimes they behave as a solid and sometimes as a liquid. (more…)

COLUMBUS, Ohio – For the first time, researchers have found a way to inject a precise dose of a gene therapy agent directly into a single living cell without a needle.

The technique uses electricity to “shoot” bits of therapeutic biomolecules through a tiny channel and into a cell in a fraction of a second.

L. James Lee and his colleagues at Ohio State University describe the technique in the online edition of the journal Nature Nanotechnology, where they report successfully inserting specific doses of an anti-cancer gene into individual leukemia cells to kill them. (more…)

Nanotechnology – the ultimate quantum level??

By ShamsDecember 8, 2007ScienceHealth, nanometer, nanoproducts, Nanotechnology, sustainable energy technology

One nanometer equals one billionth or 10-9 of a meter. A very tiny unit of length. Nanotechnology is a multidisciplinary field of applied sciences where scientists are trying to understand matter on atomic or molecular scale, a very fine level. Most probably the ultimate quantum level. The aim is to develop devices within that tiny […]
