Изучение кинетики проводилось при помощи системы регистрации, основанной на стрик-камере с пикосекундным разрешением (до 15 пс) C10627-13 Hamamatsu Photonics, сопряженной с волоконно-оптическим спектрометром, при пикосекундном лазерном возбуждении. В ходе эксперимента было зафиксировано изменение кинетики затухания флуоресценции, выраженное в появлении дополнительных компонент времен жизни флуоресценции. Количество компонент и длительность времени жизни изменялись при взаимодействии с клетками и в зависимости от pH. Так, при pH 2 было зафиксировано наличие двух времён жизни флуоресценции: 5 нс, что соответствует молекулярной форме в растворе, и 1,5 нс, что соответствует связанному состоянию молекулы фталоцианина. Так как кроме наночастиц в растворе других возможных объектов связывания нет, то, с большой степенью достоверности, можно предположить, что связывание происходит именно с наночастицами. Исследование времени жизни флуоресценции наночастиц фталоцианина алюминия в макрофагах показало наличие двух компонент порядка 9 нс и 4,5 нс. Была предложена модель перехода поверхностных молекул фталоцианина алюминия из пара- в ортоположение относительно поверхности кристаллической наночастицы.</p></abstract><trans-abstract xml:lang="en"><p>This work is dedicated to the study of the photoluminescence kinetics of aluminum phthalocyanine nanoparticles in colloidal solutions at different pH and in the interaction with immune cells (macrophages). For measurements we used a registration system based on Hamamatsu streak camera (C10627-13 Hamamatsu Photonics) with picosecond temporal resolution (15 ps), conjugated with the fiberoptic spectrometer and picosecond laser pumping. The changes in fluorescence decay kinetics as additional lifetime components of fluorescence were found during the experiment. The number of components and duration of lifetimes changed while interacting with cells and depends on pH. At pH 2 the presence of two fluorescence lifetimes was recorded: the first one was 5 ns, which corresponded to the molecular form in solution, and 1.5 ns, which corresponded to bound state of phthalocyanine molecules. Due to the absence of other possible objects for bounding in the solution except of the nanoparticles we can suggest with a high degree of accuracy that the bounding occurs with the very these nanoparticles. Analysis of the fluorescence lifetimes of aluminum phthalocyanine nanoparticles in macrophages indicated the presence of two components: 9 ns and 4.5 ns. A model of surface molecules transitions from parallel to perpendicular position, regarding to the plane of the crystal nanoparticle was proposed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>фталоцианин алюминия</kwd><kwd>фотолюминесценция</kwd><kwd>наночастицы</kwd><kwd>иммунокомпетентные клетки</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminum phthalocyanine</kwd><kwd>photoluminescence</kwd><kwd>nanoparticles</kwd><kwd>immune cells.</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">Vasilchenko S.Yu., Volkova A.I., Ryabova A.V. et al.
