Fingerprints + Super Glue = Nanofibers
Fingerprints + Super Glue = Nanofibers: "Chemical engineers at Penn State have accidentally discovered a new and versatile way to make nanofibers starting from human fingerprints and Super Glue. They were able to build not only nanofibers, but also nano-sized flat sheets or spheres. This new method will first be used in medical applications such as drug delivery.
