Based on an interfacial assembly strategy, a giant proteinosome was successfully fabricated by using protein-surfactant as building blocks, which formed a thin protein layer as a membrane. This approach of making protein assemblies was very facile, and it was very convenient to remove the templates of oil and get water-filled proteinosomes by dialysis. Through modifying acceptor and donor chromophores on the protein monomers, an efficient artificial light-harvesting system was successfully fabricated on the proteinosome, which was a scaffold for efficient light harvesting. Furthermore, the on-off switchable energy transfer was realized by protein folding and unfolding. The efficient artificial light-harvesting systems we designed as the potential platforms could be utilized for biomaterials.
基于界面组装策略，以蛋白质-表面活性剂为构建单元成功制备了巨型蛋白质体，其形成了一层薄的蛋白质层作为膜。这种制备蛋白质组装体的方法非常简便，通过透析去除油模板并获得水合蛋白质体也很方便。通过在蛋白质单体上修饰受体和供体发色团，在蛋白质体上成功构建了高效的人工光捕获系统，该蛋白质体是高效光捕获的支架。此外，通过蛋白质的折叠和展开实现了能量转移的开关切换。我们设计的高效人工光捕获系统作为潜在平台可用于生物材料。
