Abstract

Composite materials with unique architectures are ubiquitous in nature, e.g., marine shells, sponge spicules, bones, and dentine. These structured organic-inorganic systems are generated through self-assembly of organic matter (usually proteins or lipids) into scaffolds, onto which the inorganic component is deposited in organized hierarchical structures of sizes spanning several orders of magnitude. The development of bio-inspired materials is possible through the design of synthetic bottom-up self-assembly methods. Knowledge of the structure is required in order to assess the efficiency of their design and evaluate their properties. This chapter reviews the main methods used for structure determination of natural and synthetic inorganic biomaterials, namely, X-ray diffraction and scattering and electron diffraction and microscopy (TEM, SEM), as well as the AFM and CSLM microscopy methods. Moreover, spectroscopic (IR, NMR, and Raman) and thermal methods are presented. Examples of biomimetic synthetic materials are used to show the contribution of single or multiple techniques in the elucidation of their structure.

无机生物材料的结构表征。
具有独特结构的复合材料在自然界中无处不在,如海洋贝壳、海绵针状体、骨骼、牙本质等。这些结构化的有机-无机系统是通过有机物质(通常是蛋白质或脂质)自组装成支架而产生的,无机成分沉积在支架上,形成跨越几个数量级的有组织的分层结构。生物启发材料的发展是可能的,通过设计合成自下而上的自组装方法。为了评估其设计的效率和评估其性能,需要了解结构。本章综述了用于测定天然和合成无机生物材料结构的主要方法,即x射线衍射和散射,电子衍射和显微镜(TEM, SEM),以及AFM和CSLM显微镜方法。此外,还介绍了光谱(红外、核磁共振和拉曼)和热方法。仿生合成材料的例子被用来展示单一或多种技术在阐明其结构方面的贡献。

期刊介绍: Molecular biology has been providing an overwhelming amount of data on the structural components and molecular machineries of the cell and its organelles and the complexity of intra- and intercellular communication. The molecular basis of hereditary and acquired diseases is beginning to be unravelled, and profound new insights into development and evolutionary biology have been gained from molecular approaches. Progress in Molecular and Subcellular Biology summarises the most recent developments in this fascinating area of biology.
