  • Title: Self-assembled gold nanoshells on biodegradable chitosan fibers.
    Author: Wang RH, Hu ZG, Liu Y, Lu H, Fei B, Szeto YS, Chan WL, Tao XM, Xin JH.
    Journal: Biomacromolecules; 2006 Oct; 7(10):2719-21. PubMed ID: 17025344.
    Abstract:
    A novel chitosan fiber core/gold shell structural organic-inorganic composite was presented via a facile and eco-friendly approach. The chitosan fiber and gold/chitosan composites were characterized with the assistance of scanning electron microscopy and transmission electron microscopy observations. The chitosan fibers used in this study were 50 nm to 5 microm in diameter and up to hundreds of micrometers in length. The gold shells were typically 20-50 nm in depth, and their lattice fringes obliquely intersecting at an angle of 60 degrees were displayed. The formation mechanism of the as-fabricated chitosan fiber core with gold as the shell structural composites was also schematically discussed.
