...er cells," Viator said. For example, he said, gold nanoparticles -- particles only a few millionths of a millimeter wide -- could be attached to the cells using proteins that bind to special receptors on the cells' membranes. With their own photoacoustic signature, the gold particles would then signal the presence...
