Developing Gold Nanoparticles Patterns with DNA

Organizing Gold Nanoparticles with DNA. ‘Tiny billionth-of-a-meter sized clusters of gold atoms — gold “nanoparticles” — are being widely studied by scientists. They have many useful potential applications, from carriers for cancer-treatment drugs to digital data storage. But many of these applications, particularly those in electronics, require that the nanoparticles form ordered arrays that can be hard to achieve. At Arizona State University (ASU), researchers have discovered that grids made of DNA strands are excellent templates for neatly organizing gold nanoparticles.’
