Researchers to create materials from the silk, which may one day heal wounds and simultaneously serves Materials for bulletproof vests.
A material which can be stretched by three times to six times the size, while maintaining the hardness, stiffness and elasticity, and can also easily be biodegradable and biocompatible. Such material is invaluable as a costume for a successful and rapid healing of wounds or as a band for pregnant women.
Researchers at Cornell University say they have made significant progress in establishing a base polymer of silkworm silk, which has better properties.
According Dotsevi Sogah, professor of chemistry and chemical biology at Cornell University, they have developed in the laboratory of materials which have properties that greatly exceed natural. Sogaha graduate student, Osman Rathore, the results showed the effects of polymerization of peptide building blocks, based on the material of natural silk from the silkworm, August 27 at the national meeting of the American Chemical Society in McCormick, Chicago. The theme of his speech entitled: Novel biomolecular materials based on silkworm silk.
In the 1950s, Nobel laureate Linus Pauling deduced the structure of the basic structure of silkworm silk. Within the crystal structure of silk attended regular folding protein that is made by the action of amino acids in which the molecular chain periodically transformed, creating an adaptive properties of this material. Group Sogaha actually bypassed the action of amino acids, thereby creating a molecular hybrid composite structure of natural and artificial structures. Natural silk molecules were combined with synthetic molecules in hard and soft consistency.
Artificial molecules were obtained from a large database of materials, including polyethylene oxide, polypropylene oxide, polyethylene and nylon. Thus chemists Cornell University created new materials which are extremely flexible, a large tensile strength and are soluble in water.
For example, the average tensile load (before the destruction of the integrity of) materials in laboratory tests was found to be 300 percent of normal size, and one sample was able to stretch out a 600 percent!
The scope of the material extensive. They#39;ll likely be in the textile industry, where its adaptive capacity and the elastic force required to create a bullet-proof vests. Biomedical use may be possible to create a material counterpart of the human biological system (artificial leather). Hybrid silk films could be used as Biosuit for normal wound healing of burns and injuries.
Very durable, lightweight, pressing and do not cause allergies, could be created maternity belts, which on one hand will protect the fruit from any physical exertion and injuries, and the other will not give much stretch and dangle belly during pregnancy.
Another investigated the possibility of using v is the creation of a hybrid silk that could be absorbed indefinitely. Such a surface would be invaluable for experimentation and research.
