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…)

Nanotechnology – the ultimate quantum level??

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 […]
