Other scientists have mimicked the molecular design of spider silk by synthesizing their own from a commercially available substance (polyurethane elastomer) treated with clay platelets only one nanometer (a billionth of a meter) thick and only 25 nanometers across, then carefully processing the mixture to create synthetic spider silk. This work has been funded by the Inst.i.tute for Soldier Nanotechnologies at the Ma.s.sachusetts Inst.i.tute of Technology because the military applications are considered of such high importance.
