An individual nanoparticle, part of a pattern in a new technique called rapid electrokinetic patterning. [Image 1 of 3 related images. See Image 2.] More about this Image This image was taken from a video illustrating a new technique developed by researchers at Purdue University that uses a laser and holograms to precisely position clusters of numerous tiny particles within seconds, representing a potential new tool for analyzing biological samples or creating devices using "nanoassembly." The red dots are individual particles. The technique, called rapid electrokinetic patterning, is a potential alternative to existing technologies because the patterns can be more quickly and easily changed. Manipulating and assembling micro- and nanoparticles is important for a variety of micro-engineering applications including developing lab-on-a-chip technologies and creating crystalline particle architectures.
