Self-assembling nano boxes open the door to "smart" particles for medicine, manufacturing While it is relatively straightforward to build a box on the macroscale, it is much more challenging at smaller micro- and nanometer length scales. At those sizes, three-dimensional (3-D) structures are too small to be assembled by any machine and they must be guided to assemble on their own. And now, interdisciplinary research by engineers at Johns Hopkins University in Baltimore, Md., and...
