Scientists Fold DNA into Möbius Strips



A Möbius strip is a ribbon of material that has only one side. A group of nanotechnology researchers experimenting with manipulating tiny objects was able to reshape a DNA strand into a Möbius strip.

The ability to create complex structures on the tiniest of scales is one of the great challenges of nanotechnology. In particular, chemists are looking for particular topological structures, or structures that keep their basic properties no matter how much you stretch or twist them. A Möbius strip is a good example of such a structure, because no matter what you do it (short of tearing it, of course), it will always have only one side.
