1000x Thinner than Human Hair

As their name suggests, nanofibers are tiny fibers with many applications in science. From drug delivery to detecting and capturing cancer cells in the blood to making batteries more efficient, nanofibers has it all covered. Could these tiny structures be glue that holds our technology and maybe even our bodies together in the future? Who knows. But for now, you can wear them as a necklace as a reminder of their potential. This piece also makes a great gift for physicists, engineers, chemists, and starry-eyed, pre-med students.
