    摘要： The present invention provides electrospun polymer fibers comprising bacteria-containing hydrogel particles. Bacteria-containing hydrogel particles are produced by crosslinking water-soluble polymers to form hydrogels and mixing them with a bacteria suspension. The crosslinking is suitable to be carried out either chemically before the addition of the bacteria suspension or physically before or after this addition. Subsequently, these hydrogel particles are electrospun together with an electrospinnable polymer solution to form fibers or fibre non-wovens.The bacteria which are located in these hydrogel particles or in the electrospun polymer fibers comprising these particles, respectively, are capable of surviving for a long period (several months) without the supply of water or cell-culture media and are simultaneously protected against the effect of solvents, for example alcohols, acetone, chlorinated hydrocarbons, ethers and toluene, which would otherwise kill said bacteria. The bacteria are suitable to be released again at any time through contact with water and to be replicated under normal culture conditions.The electrospun polymer fibers according to the present invention comprising bacteria-containing hydrogels are suitable for use in the dry storage of useful bacteria or for killing harmful bacteria. Textiles and membranes, for example, are suitable to be equipped with it. However, they are also suitable for applications in wastewater treatment, environmental protection (water pollution control), the agricultural and food sector, pharmacy, fermentation, and the building industry.

    摘要： The present invention provides a method to produce metal-containing nanoparticles enveloped with polymers, as well as particles obtainable therefrom.In the method according to the present invention, at least one anionic polymerizable monomer is polymerized in the presence of an anionic macroinitiator at room temperature. Subsequently, an aliphatic or aromatic sulfide is firstly added, followed by a solution of at least one organosoluble metal salt in an aprotic organic solvent and finally a homogeneous reducing agent. The metal cation is hereby reduced to the metal. Metal-containing nanoparticles are formed which are covalently bonded to the growing anionic polymerizates.The metal salts are preferably salts of silver, copper, gold, tin, lead, chrome or zinc, or mixtures thereof. Anionic polymerizable monomers comprise, by way of example, styrene (St), butadiene, isoprene, ethylene oxide, propylene oxide, caprolactone, lactide, glycolide, acrylates, methacrylates, bisacrylates, cyanoacrylates, amides, siloxanes, vinylpyridines or acrylonitrile.The particles according to the present invention are suitable to be used for the antibacterial finishing of polymers in textiles and materials. Furthermore, they are suitable for the production of inks. If the underlying metals are those metals that show plasmon resonance, the particles are suitable to also be applied in sensors which use the plasmon resonance effect.The metal-containing nanoparticles enveloped with polymers which are accessible using the method according to the present invention do not aggregate or agglomerate, and their physical and chemical properties remain unchanged over a long period of time.
