Использование композитов ПММА@CuFe2O4-CuO с высокой антибактериальной активностью Е. А. Ворнакова, К. В. Сулиз

By: Ворнакова, Екатерина АндреевнаContributor(s): Сулиз, Константин ВладимировичMaterial type: ArticleArticleContent type: Текст Media type: электронный Other title: Pmma@CuFe2O4-CuO composites with high antibacterial activity [Parallel title]Subject(s): полиметилметакрилаты | синтез композитов | антибактериальная активность | неорганические наночастицыGenre/Form: статьи в сборниках Online resources: Click here to access online In: Перспективы развития фундаментальных наук. Т. 2 : сборник научных трудов XVIII Международной конференции студентов, аспирантов и молодых ученых, 27–30 апреля 2021 г Т. 2 : Химия. С. 65-67Abstract: The search of new antibacterial self-cleaning composites based on inorganic nanoparticles for biomedical applications is subject of researcher special attention. The composites are formed by adding nanoparticles in polymer solution. Polymethylmethacrylate PMMA is a widely used transparent plastic material known for its applications. In present work, PMMA@CuFe2O4-CuO composites with high antibacterial activity were synthesized. Nanoparticles CuFe2O4-CuO were obtained by electric explosion of two twisted wires in oxygen containing atmosphere. The mass ratio of Cu/Fe metals was 70/30, 34/66, 50/50. Nanoparticles were characterized by transmission electron microscopy and Vis-microscopy, X-ray diffraction and sedimentation analysis. The antibacterial activity of PMMA@CuFe2O4-CuO composites was determined against E.coli AATCC 25922. The PMMA@CuFe2O4-CuO composites are a promising material for antibacterial protection technologies and for fighting drug-resistant bacterial strains.
