Popis: In the present study, fluorescent gold nanoparticles (Flu Au-NPs) were synthesized via simple and ecofriendly green route using extract of brown algae Sargassum longifolium (S. longifolium). Characterization of synthesized Au-NPs was undertaken. The characteristic absorption peak of Au-NPs was in range 530 nm in UV-vis spectrum. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) allow the visualization of the morphological and structural character of Au-NPs. The mean particle size was calculated to be 17-50 nm. Energy dispersive X-ray spectroscopy analysis (EDAX) confirmed the presence of pure gold in the synthesized Au-NPs. The X-ray diffraction (XRD) pattern showed the face-centered cubic (FCC) nature of Au-NPs. Fourier transform infrared spectrometer (FT-IR) showed the characteristic peaks of different biocomponents in the brown algae S. longifolium extract which acted as stabilizing or capping agents of Au-NPs.
