Web of Silk Nano Fibers (IMAGE) Tufts University Caption A new bioinspired process developed at Tufts University combines top-down and bottom-up assembly to turn silk protein into materials that are easily programmable at the nano-, micro- and macro-scales; ultralight; and robust. This web of silk nano fibers was able to sustain a load 4,000 times its own weight. Credit Silk Lab / Tufts University Usage Restrictions For non-commercial use only with attribution.
