Success for nanotech medical computer
The sci-fi vision of a molecular medical team that can be injected into a patient, coursing through his bloodstream to diagnose a disease and treat it, has taken a step nearer to reality, a study published on Wednesday says. An Israeli team says it has made a computer made of DNA that, in controlled lab conditions, identified lung- and prostate-cancer cells and combatted them with a molecule based on an anti-cancer drug. (Professor) Shapiro acknowledged, though, "it may take decades" before a version of this prototype emerges which will be okayed for humans.
