Early diagnosis of a heart attack may now be possible using only a few drops of saliva and a new nano-bio-chip designed by John McDevitt, of the University of Texas. The nano-bio-chip assay, the size of a credit card, could be used to analyse a patient's saliva on board an ambulance, at the dentist's office or at a chemist's shop, helping save lives and prevent damage from cardiac disease.
