scientifically native, biocompatible , polymers from natural proteins, for example, collagen or chitosanatural chitin, are best suited for this role. of the most common polymers. on earth , such materials provide one of the best biocompatibility properties, since they are found in nature, including in the body, and humans in particular. well , for example, polylaxide material they decompose. yes, lactic acid, which is easily resorbed in the body, is excreted. naturally , different shapes can be transferred to the same polymer and a volumetric sponge of any size or a hollow tube that repeats the trachea or blood vessels can be obtained, and with the help of an apparatus for electrospinning polymer can be stretched into thinner. an almost invisible thread. we obtain non-woven polymer materials from solutions by electrospinning. this is such a method in which a polymer solution is subjected to a high constant voltage. in our case, the solution is drawn into a thin stream , the solvent evaporates and dry fibers are deposited on the collecting electrode, which is presented here. here it is in

decade of science technology are not developing new ways to produce biodegradable plastic based on chitosanhe size of landfills 400 million tons of plastic waste dump and lie down. it will be there for 300 years. according to the most optimistic estimates , the percentage of ordinary plastic that decomposes from these four hundred million tons of polymeric materials falls on the packaging materials in this plastic bag and the packaging of large-sized various products of this bottle. it is not surprising that the ocean is already littered with bottles and small plastic chips, scientists see a way out in the creation of biopolymer packaging. its composition includes plant components, thanks to which bioplastics disintegrate in just a few years into molecules. our scientists are also working on the creation of rapidly degradable polymers with starch. we received packaging materials, transparent, it is durable during testing, the film was placed in an environment with a large number of soil fungi, another black mold for 28. 7 days, there were no traces of the biopolymer, the material completely

the biopolymer sodium alginate, which is isolated from the brown algae of the white sea and the chitosanut exceptional materials in terms of properties. and such an airiness of these qualities gave him the name airgel. it is able to serve as an excellent conductor and deliver medicinal substances to the diseased organ. for of this, the airgel is injected into the composition of the early dressing with the drug, we model the surface and evaluate how the release occurs. the oily substance, is it slow enough in therapeutic lidoses that this happens in real practice and the airgel and the nano-plaster will surpass the classic dressings, because both agents do not need to be changed and removed from the affected area. skin over time, they resolve according to forecasts. chemists will take another couple of years and unique developments will go on sale. everything new is well forgotten. petrovich what's up? education again and how many hours per week in one word questions many try? you are watching news on the russia channel with you nikolai zubchik. hello , let's talk about the main thing tod
