Researchers from Delft University of Technology’s Kavli Institute of Nanoscience have discovered how to use the motors of biological cells in extremely small channels on a chip. Based on this, they built a transport system that uses electrical charges to direct the molecules individually. To demonstrate this, the Delft researchers sorted the individual molecules according to their color. Professor Hess of the University of Florida has called the Delft discovery “the first traffic control system in biomolecular motor nanotechnology”. The research findings will be published in Science on May 12.
