Researchers have developed a relatively fast, easy and inexpensive technique for inducing nanorods to self-assemble into aligned and ordered macroscopic structures. This technique should enable more effective use of nanorods in solar cells, magnetic storage devices and sensors, and boost the electrical and mechanical properties of nanorod-polymer composites.
