Hand-held scanning devices | Spinning a good tale | The Economist:
BIOTECHNOLOGISTS have long dreamed of creating a “lab on a chip” that would pack the power of a full-scale analytical laboratory into an object as small and as easy to use as the hand-held scanners familiar to fans of science fiction. Such a device might detect biological weapons, run genetic tests or sniff out contaminants. Staff at clinics could use it to screen people for infectious diseases. Police could perform on-the-spot drug tests; paramedics, roadside diagnoses.
