Scientists in Japan have created what may be the smallest scissors in the world—molecular clippers that are opened and closed with light.
These novel shears could help control genes, proteins and other molecules in the body, researchers said.
The scissors are just three nanometers, or billionths of a meter, long. This makes them more than 100 times smaller than a wavelength of violet light.
Just like real shears, the molecular device that researcher Takuzo Aida at the University of Tokyo and his colleagues have designed consists of a pivot, handles and blades. (LiveScience)
