Transmission electron micrographs of structured aggregates of gold nanoparticles of different sizes. Shown are symmetric spherical aggregates with gold nanoparticles of (A) 60 and 15 nm; (B) 50 and 10 nm; and (C,D) 60, 15, and 5 nm. The gold nanoparticles were aggregated through the linkage of synthetic oligonucleotides that were functionalized onto their surfaces. Images were collected using the Philips/FEI CM200 transmission electron microscope (TEM) in the Beckman Microscopy Suite.
