Для синтеза биметаллических наночастиц Ag-Fe использовали совместный электрический взрыв серебряной и железной проволок в атмосфере аргона. Морфологию и размер наночастиц и их агломератов определяли методом просвечивающей электронной микроскопии. Для определения среднего размера наночастиц по данным электронной микроскопии строились гистограммы распределения частиц по размерам, которые аппроксимировали нормально-логарифмическим законом. Фазовый состав определяли с помощью рентгенографического метода. Цитотоксическое действие наночастиц определяли при помощи MTT-теста на культурах базальных клеток нейробластомы мыши Neuro 2a и гистиоцитарной саркомы мыши J 774. Результаты. При совместном электрическом взрыве серебряной и железной проволок в атмосфере аргона были получены сферические частицы размером 72 нм. Показано, что серебро и железо неравномерно распределены по частицам. Встречаются участки, обогащенные одним из компонентов, с четкими границами разделения фаз, или «янус»наночастицы. На дифрактограмме образца основные рефлексы соответствуют фазам металлического Ag и Fe. Водные суспензии наночастиц отдельных металлов серебра и железа в меньшей степени снижали жизнеспособность клеток по сравнению с биметаллическими наночастицами. Наибольшую дозозависимую противоопухолевую активность продемонстрировали наночастицы Ag-Fe. Более высокая скорость коррозии биметаллических частиц Ag-Fe по сравнению с монометаллическими наночастицами обусловлена большей площадью контактов между металлическими фазами в «янус»-наночастицах, которые определяют большее число центров коррозии в биметаллических наночастицах. заключение. В результате электрического взрыва проволок из несмешивающихся металлов железа и серебра были получены биметаллические наночастицы Ag-Fe со структурой «янус»-частиц. Наночастицы Ag-Fe демонстрируют более высокую противоопухолевую активность, чем отдельные металлы, из которых они состоят, и представляют собой перспективный материал для борьбы с раковыми клетками.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of the study was to analyze the antitumor activity of magnetic bimetallic Ag-Fe nanoparticles having the structure of Yanus particles produced by the electrical explosion of wires. material and methods. For the synthesis of bimetallic Ag-Fe nanoparticles, a simultaneous electric explosion of silver and iron wires in an argon atmosphere was used. The morphology and size of the nanoparticles and their agglomerates were determined by transmission electron microscopy. To determine the average size of nanoparticles, particle size distribution histograms approximated by log-normal distribution were plotted. The phase composition was determined using x-ray method. The cytotoxic effect of the nanoparticles was evaluated by MTT assay using mouse neuro-2a (N2a) neuroblastoma cell lines and J774 histiocytic sarcoma cell lines. results. In case of simultaneous electric explosion of silver and iron wires in an argon atmosphere, the spherical 72 nm particles were obtained. Silver and iron were shown to be unevenly distributed in particles. There were areas enriched with one of the components with clear boundaries of phase separation or Janus nanoparticles. On the diffractogram of the sample, the main reflections correspond to the phases of metallic Ag and Fe. Aqueous suspensions of monometallic Ag and Fe nanoparticles reduced cell viability to a lesser extent than bimetallic nanoparticles. Ag-Fe nanoparticles showed the highest dose-dependent antitumor activity. The higher corrosion rate of bimetallic Ag-Fe particles compared to monometallic nanoparticles was due to the larger contact area between metallic phases in Janus nanoparticles, which determined a larger number of corrosion centers in bimetallic nanoparticles. conclusion. As a result of an electric explosion of wires from immiscible metals of iron and silver, bimetallic Ag-Fe nanoparticles with Janus particle structure were obtained. Ag-Fe nanoparticles exhibite higher antitumor activity than the individual metals from which they are composed and are a promising material for the fight against cancer cells.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>электрический взрыв проводников</kwd><kwd>«янус»-наночастицы</kwd><kwd>сегрегированная структура</kwd><kwd>мтт-тест</kwd><kwd>металлы железа</kwd><kwd>металлы серебра</kwd><kwd>электронная микроскопия</kwd><kwd>биосовместимость</kwd><kwd>cинтезированные наночастицы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>electric explosion of wires</kwd><kwd>Janus nanoparticles</kwd><kwd>segregated structure</kwd><kwd>mtt assay</kwd><kwd>mtt-test</kwd><kwd>iron metals</kwd><kwd>silver metals</kwd><kwd>electron microscopy</kwd><kwd>biocompatibility</kwd><kwd>synthesized nanoparticles</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Witte K., Müller K., Grüttner C., Westphal F., Johansson C.
