This paper described the design of materials based on DNA and biomimetic membranes fluorescently labelled with an optically active phytomolecule: chlorophyll a. The formation of DNA-constructs was investigated by UV-Vis absorption and fluorescence emission spectroscopy, by using the spectral fingerprint of chlorophyll. Dynamic Light Scattering (DLS) measurements revealed the nano-scaled size of the developed materials. The chemiluminescence method demonstrated the antioxidant properties of these DNA-based constructs. These findings highlighted the potential use of the obtained hybrids to develop new structures for biophotonics’ applications..
