RNA array
These images show some of the RNA shapes formed in Peixuan Guo's lab at Purdue. The first three abstract shapes - monomers, dimers and trimers - are further illustrated with the analogy of human figures grasping each others' arms (see insets in figures A, B and C). Guo's team has found a way to make these elementary shapes form more complex, 3D structures such as the array in figure D. Such arrays might form tiny scaffolding on which to construct nanotech devices. Credit: Purdue University graphic/Guo Laboratories
