چکیده

В работе методом ионотропного гелеобразования синтезированы стабильные наночастицы хитозана. Изучены свойства образца хитозана - определены его степень дезацетилирования (83,7%), а также относительная и характеристическая вязкости растворов. Определены размеры наночастиц дзета-потенциал динамического рассеяния света. Проведено исследование влияния соотношений реагентов триполифосфата натрия на средний диаметр синтезированных частиц дзета-потенциал. Получены спектры образцов в области 400-800 нм, свидетельствующие об образовании агрегатов при определенных соотношениях реагентов.
