For Super-Tough Spider Silk, Just Add Titanium

A team of scientists at the Max Planck Institute of Microstructure Physics in Germany has been experimenting with ways to infuse biopolymers with different kinds of metals. Finding some success with their tests on spider silk, the team was able to improve the tensile strength of the fibers, increasing the amount of energy required to break a strand as much as ten times. "Spider silk is not a practical engineering material, but materials scientists are trying to produce artificial fibers that mimic its properties. If they succeed, the result could be super-tough textiles. Knez thinks the technique has more immediate potential for toughening other biomaterials such as collagen. 'Mechanically improving collagen using our technique might open several new possible applications, like artificial tendons.'"

    Can someone tell me which insects contain the most titanium, and where can I get some to feed my pet spider? I've got him weaving me a hammock in my living room, but it isn't up to holding my weight yet. Maybe I'll try mixing titanium dioxide with that damn cornstarch in the kitchen that the moths got into.

    For now, they're just coating existing webs with a thin film of titanium oxide. Soon, some bright scientist will have the wonderful idea of "hey, if we can just genetically modify the spiders to metabolize titanium and use it in building webs..."

    Then the slashdot tags WhatCouldPossiblyGoWrong and IForOneWelcomeOurNewInsectOverlords will be back in vogue.

    What color is titanium when you mix it with flesh?

    It would most likely be bright white, like titanium dioxide. So the super-soldiers of the future will look like they've been doused in suntan lotion.

  11. Nexia by Baby+Duck · · Score: 2, Insightful

    Nexia Biotechnology used to breed genetically modified goats that produce Golden Orb spider silk proteins in their milk glands. They would milk the goats like normal, sift the proteins out, and then mechanically spin the threads. They wanted to use it for medical sutures, bullet-proof vests, and stuff like that. They eventually wanted to genetically modify plants they could just grind up to get the proteins out of their leaves.

    Anyway, I lost $1000 investing in that company. Seems NANOTUBES could do everything the spider silk could do, only better, and possibly in even more applications.

      You mean creepier than adding bacteria and calf stomach-juices to goat milk, letting it stand in the heat until all the milk has transformed into some bacteria-digested firm mass, and then eatin that mass, including the bacteria??

      I would be incredibly disgusted by that if I didn't already know that quantitatively there are more genetically-unrelated organisms in a given human being than that person's own genetically-related cells. Without micro-organisms our digestive tract wouldn't even work, and so micro-organisms working over things like cheese is little more than external pre-digestion. (For that matter so is cooking, which anthropological studies have been linking to be one of the more significant factors in the transition of early humanity from being 'just another primate' to the most advanced animal the biosphere has produced.)

    Fyi, there are many differently-colored copper compounds and even more iron compounds. Iron is especially versatile because of its different oxidation states.

    So anyways, TiO2 is white, but it is not something your body could use- it is as inert as glass, basically. simply injecting it into the skin would do nothing except maybe cause some local psoriasis. Getting Ti into the organic side of things would usually require TiCl4, which is colorless, or an ester of Ti (also colorless). TiCl3 is dark red but again, not something your body would be able to do anything with. There simply aren't any biological processes in the body that use Ti.

    The one interesting thing about TiO2 that I can come up with would be that if you covered someone with it and imaged them in UV light, they would be almost completely black, as TiO2 (like zinc oxide) converts UV to heat. And that's why it's used in sunblock.
