  • 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......

    Metal wires are of great significance in applications such as three-dimensional (3D) printing, soft electronics, optics, and metamaterials. Ga-based liquid metals (e.g., EGaIn), though uniquely combining metallic conductivity, fluidity, and biocompatibility, remain challenging to be spun due to their low viscosity, ......
