"В представленной работе получены углеродные квантовые точки методом микроволнового синтеза на основе лимонной кислоты и L-цистеина. Полученные частицы были охарактеризованы методами электронной и зондовой микроскопии, методом динамического рассеяния света и инфракрасной спектроскопии с Фурье преобразованием. Спектрально-люминесцентные свойства были исследованы для исходного раствора, а также растворов, полученных в результате диализа синтезированного продукта. Показано, что все образцы демонстрируют одинаковые оптические свойства. В то же время измерение квантовых выходов показало, что лучшей флуоресцентной способностью обладают углеродные точки, прошедшие через диализную мембрану. "
