A Traffic Control System For Molecules

Roland Piquepaille writes "Our cells contain small protein factories which have to deliver materials inside the cell via a network of microtubules. And the transportation is carried out by biomolecular motors. Now, researchers from Delft University of Technology in the Netherlands have built a traffic control system able to force individual molecules to choose between 'roads' by applying strong electrical fields locally at Y-junctions. This traffic control system can potentially lead to new nano-fabrication techniques. Read more for additional references and pictures showing how this traffic system works."

Re:What took so long?

Well (disclaimer: I did not really read any of the articles), dielectrophoresis seems a 'static' separation technique, to influence position of particles, and this stuff from Cees Dekker seems a sort of dynamic procedure to influence flow of particles, which is a whole step more complex. I would take 10 years to go from one to the other ;)

On a different note, I am a bit dissappointed that it is the same Cees Dekker who is a (or better: the only) big promotor in the Netherlands of the idea of Intelligent Design. This guy is doing such amazing research, that you start to wonder how he could ever combine this with the not very well-founded theory that ID is.
