Провести анализ структурных, магнитных и цитотоксических свойств наночастиц магнетита (МНЧ), приготовленных методом электровзрыва проводников и хранящихся в защищенном от света месте при комнатной температуре (влажность 65 ± 15%, атмосферное давление 760 ± 20 мм рт. ст., температура 22 ± 4 °С) в течение 10 лет.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Свойства МНЧ изучали с помощью рентгеноструктурного анализа (РСА), просвечивающей электронной микроскопии (ПЭМ) с исследованием электронной дифракции на выбранной области (SAED) и магнитометрии с вибрирующим образцом (VSM). Жизнеспособность мононуклеарных лейкоцитов крови человека определяли окрашиванием 0,4%-м раствором трипанового синего после 24-часового сокультивирования с нанопорошком.</p></sec><sec><title>Результаты</title><p>Результаты. Расчетный размер частиц практически не изменился после 10 лет хранения. Картины электронной и ренгеновской дифракции показали, что кристаллическая природа сохранялась в течение 10 лет. Диаметр кристаллической части МНЧ, определяемый, как область когерентного рассеивания ренгеновского излучения (DОКР,) был близок к размеру частиц, определенному с помощью ПЭМ (DTEM), что свидетельствует об их высокой кристалличности. Намагниченность насыщения (MS) для порошка МНЧ после 10 лет хранения оказалась неожиданно выше, чем для свежеприготовленного порошка МНЧ. Приведенная остаточная намагниченность (MR/MS) была одинаковой в пределах погрешности измерений для обоих образцов. При длительном исследовании in vitro цитотоксическое влияние МНЧ не установлено.</p></sec><sec><title>Заключение</title><p>Заключение. Кардинальные изменения структурных, магнитных свойств МНЧ после 10-летнего хранения не обнаружены. Сделан вывод о 10-летней стабильности электровзрывного нанопорошка магнетита, которая может быть полезна в плане его экологической безопасности и биомедицинских приложений.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To analyze the structural, magnetic, and cytotoxic features of magnetite nanoparticles (MNPs) prepared by the exploding wire method and stored in a dark place at ambient temperature (65 ± 15% humidity, air pressure 760</p></sec><sec><title>± 20 mm Hg</title><p>± 20 mm Hg., temperature 22 ± 4 °C) for 10 years.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. The properties of MNPs were analyzed by X-ray diffraction (XRD), transmission electron microscopy (TEM) and selected area electron diffraction (SAED), and vibrating-sample magnetometer (VSM). Viability of human blood mononuclear leukocytes was determined using 0.4% trypan blue staining after 24-hour culture with the nanopowder.</p></sec><sec><title>Results</title><p>Results. The calculated size of the particles remained almost unchanged after 10 years of storage. The XRD and SAED patterns showed that crystallinity was preserved for 10 years. The diameter of the crystalline component of MNPs (DXRD) was close to the particle size determined by TEM. It confirms high crystallinity of the tested nanoparticles. Saturation magnetization (MS) of the MNP powder after 10 years of storage was unexpectedly higher than that of the as-prepared MNP powder. Reduced remanent magnetization (MR / MS) was equal for both samples within the margin of error. No cytotoxic effect of MNPs in vitro was detected in the long-term study.</p></sec><sec><title>Conclusion</title><p>Conclusion. No dramatic changes in the structural, magnetic, and cytotoxic features of MNPs were noted after 10 years of storage. It indicated 10-year stability of MNP powder that may be a useful feature for environment safety and biomedical applications.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>наночастицы магнетита</kwd><kwd>комнатные условия</kwd><kwd>стабильность нанопорошка</kwd><kwd>лейкоциты крови человека</kwd><kwd>цитотоксичность in vitro</kwd></kwd-group><kwd-group xml:lang="en"><kwd>magnetite nanoparticles</kwd><kwd>ambient conditions</kwd><kwd>nanopowder stability</kwd><kwd>human blood mononuclear leukocytes</kwd><kwd>in vitro cytotoxicity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Сибирского государственного медицинского университета в рамках Программы стратегического академического лидерства «Приоритет – 2030».</funding-statement><funding-statement xml:lang="en">The study was supported by Siberian State Medical University development program Priority 2030</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Farjadian F., Ghasemi A., Gohari O., Roointan A., Karimi M., Hamblin M.R.
