Abstract

                Metode baru untuk mensintesis nanopartikel emas yaitu metode green synthesis adalah metode yang sangat ramah lingkungan, murah, mudah dilakukan dan menggunakan pelarut yang aman bagi lingkungan. Aplikasi NPAu bagi kehidupan sangat luas seperti antioksidan, antibakteri, biosensor, antikanker dan lain-lain sehingga para ilmuwan berlomba untuk mencoba mensintesis NPAu. Penelitian ini bertujuan untuk mensintesis NPAu menggunakan prekursor HAuCl4 0,5 mM dan ekstrak air biji cengkeh 1%. Proses pembuatan NPAu ini dilakukan dengan mencampur larutan HAuCl4 dan ekstrak air biji cengkeh kemudian dipanaskan pada suhu 40?C dan 80?C. Karakterisasi NPAu dilakukan dengan beberapa metode yaitu spektrofotometer UV-Vis dimana didapat ?maks dari NPAu 540 nm (40?C) dan 542 nm (80?C), particle size analyzer menunjukkan ukuran partikel terkecil dari NPAu 116,8 nm dan hasil dari SEM EDS menunjukkan bentuk morfologi dari nanopartikel emas ini berupa kristal bulat dengan kandungan utamanya adalah emas murni. Kata kunci: biji cengkeh, green synthesis, karakterisasi, nanopartikel emas.                   A new method to synthesize gold nanoparticles, namely the green synthesis method, is a method that is environmentally friendly, inexpensive, easy to do and uses solvents that are safe for the environment. The application of AuNPs for life is very wide, such as antioxidants, antibacterials, biosensors, anticancer and others, so scientists are competing to try to synthesize AuNPs. This study aims to synthesize AuNPs using 0.5 mM HAuCl4 precursor and 1% water extract of clove seeds. The process of making AuNPs is carried out by mixing HAuCl4 solution and water extract of clove seeds then heating it at 40 ?C and 80 ?C. The characterization of AuNPs was carried out by several methods, namely UV-Vis spectrophotometer where the maximum wavelengths of AuNPs were 540 nm (40?C) and 542 nm (80?C), particle size analyzer showed that the smallest particle size of the AuNPs was 116.8 nm and the SEM EDS results showed that the morphological shape of the gold nanoparticles was in the form of sprerical crystals with the main content being pure gold. Keywords: characterization, clove seeds, gold nanoparticles, green synthesis.
绿色纳米金粒子(NPAu)的特性,采用丁香籽提取物
合成黄金纳米粒子的新方法是绿色合成方法,非常环保,便宜,使用安全的溶剂。NPAu对生命的广泛应用,如抗氧化剂、抗菌、生物传感器、抗癌药物等,使科学家们争相合成NPAu。本研究的目的是用HAuCl4 . 5毫米前体和1。这种NPAu的制作是混合了HAuCl4的溶液和丁香籽的提取物,然后在40度加热?C和80?NPAu描述通过一些方法,即远UV-Vis获得在哪里? max从NPAu 540 nm (40 C C)和80 542 nm(?)的最小粒子,粒子大小尺寸分析仪显示NPAu 116.8 nm和EDS闪的结果展示了这个nanopartikel黄金的形态学的形状是圆的晶体和主要是纯金含量。关键词:丁香籽,绿色合成物,特性,黄金纳米粒子。一种新的合成金纳米颗粒的方法,生命的阿姨的应用非常广泛,所以科学家们被迫尝试合成阿姨。这个由0.5毫米的春药4毫米的春药和1%的水以丁香种子流出。制造阿姨的过程被雾雾4种解决方案和水排泄的海藻溶解然后在40 ?C和80 ?C中加热。AuNPs之characterization carried out是由好几个方法,namely UV-Vis spectrophotometer AuNPs之最高wavelengths哪里是540 nm (40 C)和542 nm (80 ? C),粒子大小分析仪那里那个《AuNPs smallest粒子大小是116。8 nm和EDS闪results那里的《黄金nanoparticles morphological形状是in The form of sprerical crystals with The玩内容身为纯黄金。字谜:characterization,丁香种子,金纳米粒子,绿色合成物。
