合成具有生物分子伴侣功能的金属纳米伴侣作为调节蛋白质构象的候选物具有良好的应用前景.尽管对金属纳米伴侣已有广泛研究,但其分子中界面金属原子对蛋白质构象的调控作用及其机制尚不清楚,这严重阻碍了对高性能金属纳米伴侣的开发.本研究以相同配体巯基丙酸(MPA)修饰的金纳米团簇Au_(25)为模型,通过界面掺杂金属原子(Cu、Cd、Ag)精准制备出了三种单原子掺杂的纳米伴侣,分别是Au_(24)Cu_(1)、Au_(24)Cd_(1)和Au_(24)Ag_(1),系统地研究了Au_(25)、Au_(24)Cu_(1)、Au_(24)Cd_(1)和Au_(24)Ag_(1)四种纳米伴侣对Aβ40折叠与纤维化的调控作用.全原子分子动力学模拟结果表明,界面掺杂金属原子(Cu、Cd、Ag)可通过范德华力和静电相互作用等弱相互作用影响与之接触的Aβ40单体的折叠.等温滴定量热分析结果进一步表明,Au_(24)Cu_(1)与Aβ40的相互作用分别是Au_(24)Cd_(1)、Au_(24)Ag_(1)和Au_(25)的1.76、2.09、16.67倍.这些不同的相互作用会导致金属纳米伴侣对Aβ折叠与纤维化的不同调节作用,四种金属纳米伴侣抑制Aβ折叠与纤维化效率依次为Au_(24)Cu1>Au_(24)Cd_(1)>Au_(24)Ag_(1)>Au_(25).本文提供了对金属纳米团簇界面金属原子如何发挥作用的微观分子见解,并为通过操纵界面金属原子来定制金属纳米伴侣提供了基础研究数据.

在过去几十年中,将二氧化碳光还原转化为有用的化学燃料(甲烷、一氧化碳和甲醇等)受到了极大的关注.然而,由于光生电荷的复合速度快,二氧化碳和水分子的共吸附不足,目前的二氧化碳光还原系统的效率还远远不能令人满意.本文报道了在疏水碳纤维纸上构建一个紧密的二维/二维石墨相氮化碳@碘氧铋梯型(S型)异质结,用于高效的二氧化碳光还原.所制备的异质结具有良好的一氧化碳选择性(77.8%)和活性(458.0μmol h^(-1)m^(-2)).良好的光催化性能归因于良好设计的S型异质结结构,提高了电荷分离效率,以及形成了气-液-固三相界面,充分保证了二氧化碳和水的同时供给.这项工作为高效光催化二氧化碳还原系统的设计提供了新思路.
