The Ringer
Prof. Gregory Rutledge speaks with The Ringer reporter Claire McNear about the science behind nanofibers and whether it's possible to create ultrathin and ultrastrong nanofibers that are invisible to the human eye, as shown in the science fiction series “3 Body Problem.” Rutledge explains that: “Given that a human hair is about 50 micrometers in diameter, a fiber 100 times smaller would be about 500 nanometers in diameter. Such fibers are routinely made by electrospinning, as well as by a couple of other technologies. Metal wires can also be drawn that small.”
