Показано, что ротационная диффузия более чувствительна к изменениям размеров частиц, чем трансляционная. Проведена сравнительная оценка этих изменений и вычислен относительный индекс агрегации по интегральным значениям автокорреляционных функций деполяризованного динамического рассеяния света. Сопоставлены результаты численного моделирования предложенного метода и его экспериментальной апробации.</p></abstract><trans-abstract xml:lang="en"><p>The method is proposed for studying the aggregation of nanoparticles in colloidal solutions, based on the estimation of the slowing-down of the rotational diffusion coefficients of nanoparticles, which are more sensitive to changes in particle size than their hydrodynamic radius, depending on translational diffusion. The possibility of a comparative evaluation of these changes and the calculation of the relative aggregation index from the integral values of the autocorrelation functions of depolarized dynamic light scattering is shown. The results of numerical simulation of the proposed method and its experimental approbation are compared.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>агрегация наночастиц</kwd><kwd>динамическое рассеяние света</kwd><kwd>ротационная диффузия</kwd><kwd>автокорреляционные функции</kwd><kwd>оптические наносенсоры</kwd><kwd>nanoparticles aggregation</kwd><kwd>dynamic light scattering</kwd><kwd>rotational diffusion</kwd><kwd>autocorrelation functions</kwd><kwd>optical nanosensors</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">Мусихин С.
