Для некоторых соединений при такой оценке предполагается дополнительное воздействие на клетки, например, освещение. Целью настоящей работы является создание установки для равномерного облучения клеточных культур в планшетах и определения эффективности новых фотосенсибилизаторов (Фс). Разработанная схема установки позволяет равномерно освещать 96-луночный планшет с облученностью до 76 мВт/см2, при этом значения температуры не превышают 43°C, что позволяет использовать ее для активации Фс. Для апробации рабочих режимов установки в качестве модельного объекта использовали цинковый фталоцианин с холиниловыми заместителями (холосенс) и клеточные культуры HEK-293 или A431. Были определены зависимости выживаемости клеток от времени облучения и концентрации Фс, а также получены изображения флуоресценции химической ловушки активных форм кислорода в клетках, испытывающих окислительный стресс вследствие фотодинамического эффекта Фс. Полученные результаты свидетельствуют о более чем двукратном различии выживаемости между клетками в экспериментальных и контрольных лунках, а также о равномерном освещении всех лунок планшета.</p></abstract><trans-abstract xml:lang="en"><p>The aim of the work is to develop a light source for uniform irradiation of cell cultures in plates and for determination of the efficiency of new photosensitizers. The designed scheme of the light source provides uniform irradiation of a 96-well plate with irradiance up to 76 mW/cm2 with temperature values not exceeding 43°C, which allows to use it for activation of photosensitizers. For approbation of the working modes of the unit, zinc phthalocyanine with cholinyl substituents (cholosens) and cell cultures HEK-293 and A431 were used as a model object. Dependences of cell survival on irradiation time and photosensitizer concentration were determined, and fluorescence images of the marker of reactive oxygen species in cells experiencing oxidative stress due to the photodynamic effect of photosensitizers were obtained. The results show a more than twofold difference in survival between cells in experimental and control wells, as well as uniform illumination of all wells of the plate.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фотодинамическая терапия</kwd><kwd>осветительная установка</kwd><kwd>фталоцианин</kwd><kwd>окислительный стресс</kwd><kwd>активные формы кислорода</kwd><kwd>флуоресцентная микроскопия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>photodynamic therapy</kwd><kwd>light source</kwd><kwd>phthalocyanine</kwd><kwd>oxidative stress</kwd><kwd>reactive oxygen species</kwd><kwd>fluorescence microscopy</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Российского научного фонда в рамках научного проекта № 24-24-00125.</funding-statement><funding-statement xml:lang="en">The research was funded by the Russian Science Foundation, project number 24-24-00125.</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">Gong L., Zhang Y., Liu C., Zhang M., Han S.
