Rapid Electrokinetic Patterning (Image 3)

An individual nanoparticle, part of a pattern in a new technique called rapid electrokinetic patterning. [Image 3 of 3 related images. Back to Image 1.]

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.
