Spectroscopic analysis and nuclear magnetic resonance for silver nanoparticles synthesized with trans-resveratrol and cis-resveratrol

The synthesis of silver nanoparticles with polyphenolic molecules (AgResvNPs) is important due to potential applications as nanocarriers of resveratrol. Silver nanoparticles were synthesized with trans-3,5,4′-trihydroxystilbene (resveratrol) and irradiated under UV light. Further AgResvNPs were char...

Description
Summary:The synthesis of silver nanoparticles with polyphenolic molecules (AgResvNPs) is important due to potential applications as nanocarriers of resveratrol. Silver nanoparticles were synthesized with trans-3,5,4′-trihydroxystilbene (resveratrol) and irradiated under UV light. Further AgResvNPs were characterized by transmission electron microscopy (TEM), energy-dispersive X-ray spectroscopy (EDS), selected area electron diffraction (SAED), UV–Vis spectroscopy, Fourier transform infrared spectroscopy (FTIR), Raman spectroscopy with surface-enhanced Raman scattering (SERS), nuclear magnetic resonance (NMR), zeta potential, and dynamic light scattering (DLS) and study of aggregation kinetic and colloidal stability for this system in water and s-DMEM and evaluate the antioxidant capacity with total phenols count assay. Ultraviolet light irradiation promotes the synthesis of AgResvNPs and modifies the conformational structure of resveratrol. NMR confirmed these changes structurally in the molecule. Applications in SERS are an important application of this system.
