  • 生物质基一维纳米材料
    定义:纳米纤维包括直径小于100纳米通过分子有序聚集形成的纳米纤丝、及直径小于1微米通过电纺、海岛等途径制备的纳米纤维。制备:(1)纳米纤丝在自然界广泛存在。多糖(如纤维素、甲壳素)、蛋白质(如蚕丝、胶原)或两亲分子可形成纳米纤丝,如纤维素纳米晶须、甲壳素纳米晶须、蚕丝中以beta折叠为基础的纳米纤丝、以胶原蛋白alpha三螺丝为基础的纳米纤丝、以及淀粉样纳米纤丝等。纳米纤维形成的类似液晶的取向、周期性结构是天然生物材料力学性能、光学性能、生物学性能的结构学基础之一,如在节肢动物的足部表层,蛋白质包覆的甲壳素纳米纤维取向排列形成梯度分布;鱿鱼牙中甲壳素纳米纤维与无机物形成层状梯度分布;“海绵骨针”中......

  • 蛋白质的纤维化组装
    在外部环境改变时,蛋白质的空间构型会发生变化,由可溶的天然态转变为不溶的纤维态,该过程被称为蛋白质的淀粉样纤维化(Amyloidosis)。[1-3] 蛋白质的淀粉样纤维化过程起始于蛋白分子的错误折叠,这些错误折叠首先生成寡聚体(oligomers),继而叠加形成原纤维(protofibrils)并最终自组装形成纤维或纤维聚集体(fibrils)。[4] 蛋白质的纤维化过程最早发现于某些疾病的病变组织中,是帕金森症、阿尔兹海默症、Ⅱ-型糖尿病等多种淀粉样变性疾病的重要致病原因。根据2014年的统计数据,淀粉样变性疾病已成为美国老年人中的第三大致......

    Marine molluscs have inspired to construct robust composites with hierarchical microstructures, and also to design artificial muscles with rapid and controllable deformation. Abalone nacre has the unique “brick and mortar” structure, whose two-dimensional (2D) “mortar” can serve both as the strong adhesive between a......

    Incorporation of nanoscale colloidal objects into three-dimensional (3D) hydrogel networks can not only reinforce the hydrogels as “colloidal cross-linkers”, but also add many extra functionalities for diverse applications. For the first time, deformable droplets of liquid metal (LM) in combination with sonication w......

    Gold (Au) crystalline microwires with an unprecedented diameter of >500 nm and an aspect ratio >400 were synthesized using L-tyrosine as a reducing and capping agent. The Au microwires possessed high conductivity and electrocatalytic activities towards glucose and Hg(II). Their large diameters and aspect ratio......

    Natural silk cocoons have fibrillary structure atseveral levels of length scales, which offered mechanical properties superior to many artificial silk materials. Despite the fact that many solvents had been endeavored to extract natural nanofibrils for the construction of functional materials, silk microfibrils have......

    Porous metal foams have been one of the most sought-after materials owing to their combination of bulk metallic characteristics (e.g., thermal/electrical conductivity and ductility) and nanometric size-effect properties (e.g., catalytic reactivity, plasmonic behavior, and high surface area). Traditional sol-gel appr......
