Abstract:

Introduction. Oxide nanoparticles activated with rare-earth cations were tested for their theranostic applications as biomarkers in nanomedicine for early cancer diagnostics. Among oxide nanoparticles ZnO based nanostructures are known to present important advantages as antimicrobial, non-irritating, and absorb odors materials. They are GRAS (‘generally regarded as safe’) materials. In this research, for the first time, we report the Samarium doped zinc oxide nanomaterials which are produced using a green method. Such a method could generate biomarkers at varying compositions based on oxide materials (ZnO) for medical and biological applications such as early cancer diagnostics. Method. a microwave-assisted phytosynthesis route by using Rosa sahandina , a wild kind of rosace family, was used to produce the biomarkers. The structural, physicochemical and morphological properties of the biomarkers were determined by using several techniques such as FTIR, UV-Vis spectroscopy. X-Ray diffraction (XRD) analysis was used to test the achievement of a pure Sm@ZnO phase with a high degree of crystallinity. Besides structural characterisations, the products were thoroughly characterised by means of complementary techniques like DLS and EDX-SEM. Results. In this work we describe properties of Sm@ZnO markers obtained by a microwave-assisted phytonanotechnology. This technique offers the biomarkers at varying compositions, which are adjusted to meet specific cancer diagnostics application in size ranges less than ۱۰۰ nanometers. Thestuy on properties of ZnO nanoparticles doped with Sm۳+ ions for applications as biomarkers in biology and medicine is ongoing. Conclusion. In our work we tested the physical, chemical and biological properties of new generation of nanoparticles based on oxides obtained by the microwave asssesisted green methods. We were able to control the size of particles, their shape and doping with Sm۳+ ions. Finally, the findings from this study highlight the potential of new nanoparticles as biomarkers in nanomedicine.
