Particle Architecture (IMAGE) Duke University Caption Researchers have created a new "oil and vinegar" approach to forming nanoparticle structures. In this conceptual model, green and blue elements repel one another. Not only does this create a boundary layer where particles tend to congregate, researchers can attach molecules to individual nanoparticles to make them more or less repulsed by an individual layer. This approach is depicted across the center of the image, while the resulting structures can be seen from different angles above and below.
