В рамках данной работы нами проведено комплексное исследование физико-химических характеристик, коллоидной стабильности и МРТ отклика синтезированного нанокомпозита, а также комплексный анализ его цитотоксичности на культуре клеток глиобластомы человека линии U251 in vitro. Показано, что синтезированный нанокомпозит вызывает дозозависимый цитотоксический эффект в отношении клеток глиобластомы человека, вызывая развитие внутриклеточного окислительного стресса и последующей инициации процесса апоптоза. Такой нанокомпозит перспективен для разработки на его основе нового тераностического агента, обладающего не только МРТ-контрастирующими свойствами, но и выраженной редокс-активностью, что обеспечивает его цитотоксический эффект и терапевтическую активность в клетке.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results of a study of a new folic acid functionalized nanocomposite cerium oxide based gadolinium-doped material as a promising material as a new MRI contrast agent. As part of this work, we carried out a comprehensive analysis of their characteristics, colloidal stability, and MRI response, as well as a comprehensive analysis of its cytotoxicity on a U251 human glioblastoma cell culture in vitro. It has been shown that the synthesized nanocomposite causes a dose-dependent cytotoxic effect on human glioblastoma cells, causing the development of intracellular oxidative stress and subsequent initiation of the apoptosis process. Such a nanocomposite is promising for the development of a new theranostic agent based on it, which has not only MRI-contrasting properties, but also a pronounced redox activity, which ensures its cytotoxic effect and therapeutic activity in the cell.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>наночастицы</kwd><kwd>церий</kwd><kwd>гадолиний</kwd><kwd>магнитно-резонансная томография</kwd><kwd>цитотоксичность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>nanoparticles</kwd><kwd>cerium</kwd><kwd>gadolinium</kwd><kwd>magnetic resonance imaging</kwd><kwd>cytotoxicity</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено за счет гранта Российского научного фонда № 22-73-10231, https://rscf.ru/project/2273-10231/.</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">Baldim V., Bedioui F., Mignet N., Margaill I., Berret J.-F. // Nanoscale. 2018.
