Functionalized metal nanoparticles are unique in nature and are being developed for its specificity in drug targeting. In the present study, aqueous extract of Sargassum myriocystum is used for the biosynthesis of gold nanoparticles (AuNPs) by the reduction of chloroauric acid. The formation of nanoparticles reaction was complete within 15 min at 76 °C. The size, shape and elemental analysis of AuNPs were carried out using UV-visible absorption spectroscopy, FT-IR, TEM, SEM-EDAX, and XRD analysis. The newly formed AuNPs are stable, well-defined, polydispersed (triangular and spherical) and crystalline with an average size of 15 nm. The biomolecule involved in stabilizing AuNPs was identified using GC-MS.
功能化金属纳米粒子在性质上是独特的，正因其在药物靶向方面的特异性而被开发。在本研究中，通过还原氯金酸，利用马尾藻的水提物来合成金纳米粒子（AuNPs）。纳米粒子的形成反应在 76°C 下 15 分钟内完成。使用紫外-可见吸收光谱、FT-IR、TEM、SEM-EDAX 和 XRD 分析对 AuNPs 的大小、形状和元素分析进行了研究。新形成的 AuNPs 是稳定的、定义明确的、多分散的（三角形和球形）和结晶的，平均尺寸为 15nm。使用 GC-MS 鉴定了参与稳定 AuNPs 的生物分子。
