Most of the natural products isolated at present are heterocyclic compounds, so heterocyclic compounds occupy an important position in the research of organic chemistry. A compound: 16961-25-4, is researched, SMILESS is Cl[Au-](Cl)(Cl)Cl.[H]O[H].[H]O[H].[H]O[H].[H+], Molecular AuCl4H7O3Journal, International Journal of Biosciences called Brown seaweed Sargassum polycystum (C. Agardh) extract as mediator in the green synthesis of colloidal gold nanoparticles from Malita, Davao Occidental Philippines, Author is Lumogdang, Leonel; Teves, Franco, the main research direction is brown seaweed Sargassum polycystum gold nanoparticle green synthesis.Recommanded Product: Hydrogen tetrachloroaurate(III) trihydrate.
One of the paradigm shifts in the field of nanotechnol. is the development of environmentally friendly, biocompatibility and green approaches in the synthesis of metal nanoparticles. In this study, the extracts of Brown seaweed, Sargassum polycystum (C.Agardh) were utilized as reducing agents in the green synthesis of gold nanoparticles. The produced gold nanoparticles were characterized using UV-visible spectroscopy, Fourier Transform IR (FTIR) spectroscopy, SEM (SEM) and Energy dispersive X-ray (EDS) spectroscopy. The different volumes of brown seaweed extract namely 25, 20, 15, 10 and 5ml when added with Tetrachloroauric acid gradually changed from color brown to ruby red, a characteristics reaction of gold nanoparticles. UV-vis spectral anal. of the gold nanoparticles showed strong peaks around 526nm to 548nm, an optical characteristic of gold nanoparticles. The presence of elemental gold was also confirmed by the EDS anal. The SEM image of the gold nanoparticles clusters of spherical morphol. with a size range of 68.5 to 240nm. The FTIR spectra of the brown seaweed mediated synthesized gold nanoparticles showed strong peaks corresponding to hydroxyl groups, and primary amines functionalities which probably acted as reducing agent, stabilizing agent and capping agent during the synthesis of gold nanoparticles.
