dc.description.abstract | Suitable properties as well as eco-friendly synthesis of photoluminescent Au nanoclusters (NCs) make them promising compounds for biomedical diagnostics and visualization applications. However, the potential photochemical activity of such agents on cancerous cells is largely unknown. The nanoclusters (BSA-Au NCs) were synthetized in the presence of BSA (an average hydrodynamic diameter was about 9.4 nm, while the size of the metal cluster was <1.3 nm according to atomic force microscopy measurements) and possessed a broad photoluminescence band at 680 nm in buffered (pH 7.2) aqueous medium. The photochemical activity was studied by adding two fluorescent probes (dihydrorhodamine or Singlet Oxygen Sensor Green) for detection of reactive oxygen species in samples irradiated at 405 nm to minimize direct excitation of the probes. The photoluminescence measurements evidenced the capability of BSA-Au NCs to generate reactive oxygen species upon light exposure, while the observed sensitivity of the photoluminescence properties might be used to indicate photooxidative processes in the medium. The viability test performed on breast cancer cells after incubation with BSA-Au NCs and subsequent irradiation revealed notable difference in induced phototoxicity between two cell lines, which was not the case after the corresponding treatment using the photosensitizer chlorin e6. | eng |
