Fluorescent properties of nanodiamonds in result of interactions of nanodiamonds with biomacromolecules in water

摘要

In the present work an influence of interactions between detonation nanodiamonds and biomacromolecules (DNA and lysozyme) on fluorescent properties of nanodiamonds was studied. Formation mechanisms of complexes of nanodiamonds with DNA and lysozyme molecules were investigated. It was found that fluorescent intensity of detonation nanodiamonds changes in different ways for nanoparticles with different surface composition. It was established that fluorescent intensity of nanodiamonds increases in case of the interaction with a sufficient number of biomacromolecules.
