Controlling the Absorption of Gold Nanoparticles via Green Synthesis Using Sargassum crassifolium Extract


Article Preview

This work controls the absorption of gold nanoparticles (GNPs) via green synthesis utilizing Sargassum crassifolium extract. The amount of seaweed extract acts as both reducing (from Au+ to Au0) and capping agent. The S. crassifolium extract is mainly composed of biomolecules such as protein and phenolic compounds which are responsible for the synthesis of GNPs. The synthesized GNPs were characterized using UV-Visible spectroscopy, Fourier Transform Infrared (FTIR) spectroscopy and Transmission Electron Microscopy (TEM). UV-Vis spectra revealed peaks around 505 nm to 544 nm which corresponds to the Surface Plasmon Resonance (SPR) of GNPs. FTIR spectroscopy analysis showed peak at 825 cm-1 and 1144 cm-1 which corresponds to the signature peaks of GNPs. Polydisperse GNPs with varied sizes (between 5 nm to 300 nm) were further confirmed by TEM analysis.
