  • Title: Simultaneous synthesis and assembly of gold nanoparticles in cuttlebone-derived organic matrix: a "green" pathway for gold nanocomposite.
    Author: Jia X, Qian W.
    Journal: J Nanosci Nanotechnol; 2008 Sep; 8(9):4370-6. PubMed ID: 19049027.
    Abstract:
    We demonstrate herein a "green" pathway for the formation of a gold nanocomposite using the cuttlebone-derived organic matrix. The gold nanocomposite is achieved through the first exposure of the organic matrix to HAuCl4 solution at room temperature and its subsequent heating at 80 degrees C. The process results in the formation of a macro porous gold nanocomposite consisting of gold nanoparticles embedded in the cuttlebone-derived organic matrix background, which shows the characteristic plasma absorption of gold nanostructures. UV-vis-IR spectrophotometer and transmission electron microscope (TEM) were used to characterize the gold nanocomposite and trace the formation process. A highlight of the research is that we adopted a nontoxic and renewable reagent of cuttlebone-derived organic matrix, which functioned as the reducing reagent, stabilizer and scaffold for the synthesis of gold nanoparticles.
