    摘要: The invention provides a method of preparation of a polymer substrate with immobilized silver nanoparticles, wherein the substrate is prepared via electro spinning of a mixture of water non-soluble polymer and a polymer linker containing Ag-reducing functional groups containing nitrogen atom having a free electron pair, and consequently, the substrate is subjected to aqueous solution of silver ions resulting in formation of silver nanoparticles covalently immobilised to the substrate via nitrogen atom of the polymer linker. Further, an antimicrobial material is described, which contains the substrate from water non-soluble polymer and polymer linker containing functional groups containing nitrogen atom with a free electron pair. Silver nanoparticles are covalently immobilized to these functional groups of.

    摘要: The present invention relates to a tissue adhesion prevention material comprising poly octylcyanoacrylate in the form of a non-woven fabric and to a method for manufacturing same, and aims to facilitate treatment of the body through the tissue adhesion prevention material, which is biodegradable inside the body and comprises an antibiotic or an anti-inflammatory, having the characteristic of a sustained-release agent, so that the antibiotic or the anti-inflammatory is slowly released as the tissue adhesion prevention material dissolves inside the body. According to the present invention, provided is the tissue adhesion prevention material in the form of the non-woven fabric and the method for manufacturing same, comprising the steps of: preparing a crude liquid for the material for the tissue adhesion prevention material by first preparing a poly octylcyanoacrylate mixture by adding poly octylcyanoacrylate to an organic solvent and mixing same, and adding a hydrophilic polymer, the antibiotic, or the anti-inflammatory to the poly octylcyanoacrylate mixture and mixing same; and obtaining the tissue adhesion prevention material in the form of the non-woven fabric by electrospinning the crude liquid for the tissue adhesion prevention material.
