...oesnt matter. So when you are trying to manipulate matter at the nanoscale, electrical fields and fluid fields may work best. By using directed assembly, we can tailor the forces acting on the nanoparticles. The ability to use several forces acting in tandem becomes important."

...A and the severity of symptoms are linked. "It's a matter of ratios: the more abnormal protein you have, the more severe the disease," Miner says.
