Offering a potential new approach to preventing deadly heart attacks and strokes Indian-origin researchers have designed a synthetic nanoparticle that can simultaneously light up invisible plaque build up inside the arteries and also treat it. Plaque build up inside arteries that generally goes unnoticed can lead to atherosclerosis -- a prolific and invisible killer. Current detection strategies often fail to identify dangerous plaques which can clog arteries over time or break off from arterial walls and block blood flow causing a heart attack or stroke. Magnetic resonance imaging (MRI) offers a potential approach for plaque visualisation but requires the use
