Stanford Medicine researchers invent an electromagnetic device that can gently sort different types of cells by levitating them to different heights. It looks like a magic trick: Cells at the bottom ...
The scientists chemically coated each graphite particle with a layer of electrically insulating silica. Polyethylene glycol (PEG) helps silica bind to the surface of the graphite. The coated graphite ...
An electromagnetic device can gently sort cells by levitating them to different heights. It looks like a magic trick: cells at the bottom of a liquid medium begin levitating, then hovering at a ...
