Researchers at the University of California, Irvine have developed a guided electrokinetic assembly technique that utilizes dielectrophoretic and electroosmotic forces for micro- and nanomanufacturing. This technique provides a new way for assembling microelectronics and living cells for tissue engineering applications.
·Assembly of living cells and organisms for tissue engineering applications
·Carbon nanotube assembly
·Nano- and micromanufacturing
·Spontaneous and quick assembly of both micro and nano parts
·Less expensive than many pick-and-place methods
Microdevices are used for a variety of applications ranging from tissue engineering to microelectronics to drug discovery. Currently, their assembly relies on slow serial steps of production such as pick-and-place or self-assembly operations. However, these methods can be expensive, time consuming, and may not work for both micro- and nanocomponents. The current microdevice assembly technology can be expensive and slow.
The researchers at the University of California, Irvine have developed a method for guided assembly, which uses an array of patterned microelectrodes to dielectrophoretically and electroosmotically assemble microscopically in aqueous solution. It combines the speed of self-assembly with the precision of directed assembly techniques in a parallel manner.
