When it comes to nanotechnology, it's not just the size of the particle that is important, but also the shape. The unique bipyramid shape of these gold nanoparticles is controlled by atoms of silver that fill in between gold atoms on the particle's surface. The particles' sharp corners may prove ideal for enhancing the performance of ultra-sensitive detection techniques, such as those used to find trace amounts of contaminants or biological markers of disease.
