This is a gold nanoparticle, brought into contact to a DNA nanostructure, sticks to chemical patches. Scientists then dissolve the assembly, separating the DNA nanostructure into its component strands and leaving behind the DNA imprint on the gold nanoparticle. Credit: Thomas Edwardson
New technique could facilitate use of gold nanoparticles in electronic, medical applications. Gold nanoparticles have unusual optical, electronic and chemical properties, which scientists are seeking to put to use in a range of new technologies, from nanoelectronics to cancer treatments.
Some of the most interesting properties of nanoparticles emerge when they are brought close together – either in clusters of just a few particles or in crystals made up of millions of them...
