Abstract:
Light-triggered redox activity of small (d = 2 nm) GdYVO4:Eu3+ nanoparticles (NPs) in aqueous solutions and lipid suspensions is reported. It has been revealed that depending on pre-treatment conditions (exposure to UV light or storage in the dark) the same NPs exhibit pro- or anti-oxidant properties. Pro-/anti-oxidant activity in aqueous solutions was evaluated by UV-vis spectroscopy using probe molecules for hydroxyl radicals (·OH) and superoxide anions (O2•-). Lipid oxidation under the effect of NPs has been also analyzed. Multi-functional GdYVO4:Eu3+ NPs are assumed to be a new theranostic agent in cancer therapy, which exhibit fluorescent properties, triggered redox activity and drug-carrier ability.
