Exotic Super Spider Silk: Now Can be Produced at Large Scale!

Biologists may have one-upped Spiderman, genetically modifying silkworms to produce spider silk with properties similar to natural spider web, a stunning achievement with vast potential medical and textile use. Recent research highlights the process that can be used for industrial production of fibres that until now could only be produced in laboratories in tiny quantities. Macolm Fraser, associate scientist said:

This research represents a significant breakthrough in the development of superior silk fibers for both medical and non-medical applications.

More Tensile, Elastic than Natural Silk

The generation of silk fibres having the properties of spider silks has been one of the important goals in materials science. That is because natural spider silks have unusual physical properties, such as much higher tensile strength and elasticity than natural silk fibres. And artificial spider silks produced by these transgenic silkworms have similar properties strength and flexibility to natural spider webbing, said the scientists who announced the development at Notre Dame in Indiana.

Bulletproof vests made of spider silk

Previously only tiny amounts of spider silks had been made in labs. But this development opens the door to viable large-scale production. Among the potential biomedical uses of the fibres: “fine suture materials, improved wound healing bandages, or natural scaffolds for tendon and ligamentrepair or replacement,” the scientists said in a statement.”Spider silk-like fibres may also have applications beyond biomedical uses, such as in bulletproof vests, strong and lightweight structural fabrics, a new generation athletic clothing and improved automobile airbags.

Silkworm and spider a winning combination

When the transgenic silkworms spin their cocoons, they aren’t making silk or spider silks, the scientists explained. Silk produced is not ordinary silkworm silk, but, rather, a combination of silkworm silk andspider silk. The genetically engineered silk protein produced by the transgenic silkworms has markedly improved elasticity and strength approaching that of native spider silk.

Remarks: I find it extremely useful in developing highly developed robotic exploration probes which can be sent to mars and other planets. A kind of highly developed terrestrial pathfinder could be build using it. Since spider silk is far better than commonaly used fibre both in tensile strength and machining properties that’s why it could be a better replacement of generally used fibres. The great advantage would be that such explorer would be very light weight mean would require less force to overhail any problem which are more often in rocky planets like mars. An insectoid design utilizing MEMS(Micro ElectroMechanical Systems) would be the best even when exploration mission is sent to titan. Due to surface tension of methane seas of titan(as some of insect can walk over surface of water) , these tiny explorers would be able to explore and detect alien life.

    Hmm..maybe we could use the material to construct a nanotube ribbon that can be used to make a space elevator?

    Stronger than steel.

  2. bruceleeeowe says:

    That could be excellent for space elevator. I would suggest that it should be concocted with nanotubes ie. Nanoengineered spider silk could be even better.

  3. Could they make it cheap enough for EVERYONE to get a bulletproof coat or shirt made of this indestructible spider silk? About 101,000 people get shot in the USA every year, with about 30 to 32000 dying. Australia banned guns after a particuliarly heinous mass shooting, and hasn’t had anything like what happens in the USA since. The NRA is so politically powerful that there is apparently nothing we can do to eliminate the ever-rising number of guns out here, but perhaps this scientific advance could lower our body count in the long run.

    Can you remember that in 2004 NRA successfully opposed the renewal of Federal Assasult Weapon Ban of 1994, which banned many features of certain semiautomatic rifles, against a compaign to make the ban permanently and expand it. I’m agree with you they are politically so powerful that we can’t do anything against them. So far, we haven’t any bulletproof vest yet..it would be continued unless Obama take adequate actions.
