DNA molecules can detect pathogens, deliver drugs

(PhysOrg.com) -- First, Cornell researchers created DNA "bar codes" -- strands of the genetic material that quickly identify the presence of different molecules by fluorescing. Now, they have created new DNA molecules that can detect pathogens and deliver drugs to cells when they form long chains called polymers.
