Установлено, что миелопероксидаза и продуцируемая ею хлорноватистая кислота вызывают разрушение ГКТ в биосистемах. Выявлено, что в присутствии ГКТ скорость окисления субстрата пероксидазой хрена и миелопероксидазой снижается. Флуоресценция, биодеградация, способность к функционализации делают ГКТ перспективными компонентами для тераностических платформ.</p></abstract><trans-abstract xml:lang="en"><p>The fluorescence of graphene quantum dots (GQDs) at various pH, temperature, and ionic strengths, as well as in the absence and in the presence of peroxidases was investigated. It was found that myeloperoxidase and the hypochlorous acid it produces cause GQD degradation in biological systems. The rate of substrate oxidation by horseradish peroxidase and myeloperoxidase was shown to decrease in the presence of GQDs. Fluorescence, biodegradation, and the ability to be functionalized make GQDs the promising components for theranostic platforms.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>графеновые квантовые точки</kwd><kwd>флуоресценция</kwd><kwd>миелопероксидаза</kwd><kwd>пероксидаза хрена</kwd><kwd>гипохлорит-ионы</kwd><kwd>биодеградация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>graphene quantum dots</kwd><kwd>fluorescence</kwd><kwd>myeloperoxidase</kwd><kwd>horseradish peroxidase</kwd><kwd>hypochlorite ions</kwd><kwd>biodegradation</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">Т.
