(PhysOrg.com) -- A major goal of nanotechnology research is to create a "lab on a chip," in which a tiny biological sample would be carried through microscopic channels for processing. This could make possible portable, fast-acting detectors for disease organisms or food-borne pathogens, rapid DNA sequencing and other tests that now take hours or days.
