摘要

This communication describes a general method for templating fungal filaments with gold nanoparticles that results in a gold replica of filaments after calcination of the biological template. During the last 500 million years, Nature has developed a multitude of structures and chemical building blocks (bio-molecules) with precise control of the function/architecture, which was essential for the survival of living organisms in practically all environments on the Earth. By using a few chemical elements such as C, H, O, N, P, S, Si and Ca, under mild conditions of temperature and pH, biological systems can form complex structures, which are hierarchically organised at the nano, micro, meso and macroscales. Excellent examples include the multifunctional siliceous skeletons of diatoms and radiolarians, the ordered microstructure based on chitin of butterfly wings or the arrangement of microcrystals of hydroxyapatite with protocollagen that forms the bones of mammals.
