Aggregation-induced emission (AIE) of a 2D protein supramolecular nanofilm exhibiting multiple functions is achieved for the first time at the air/water interface or on a solid surface at a timescale of several minutes. The mixture of lysozyme, tris(2-carboxyethyl)phosphine (TCEP) and 9,10-distyrylanthracene with two ammonium groups (DSAI) results in the rapid synthesis of a phase-transited lysozyme (PTL) AIE nanofilm, coating or ink from a neutral aqueous solution at room temperature. The multifunctionality of these waterborne biocompatible DSAI@PTL AIE materials shows some potential applications such as anti-bacterial and anti-counterfeiting for edible items or living creatures. This strategy combines the advantages of AIE with a 2D biopolymer suprastructure and provides an eco-friendly interfacial material with biological functions and applications. By introducing versatile AIE molecules with different functions and emission, the development of optically active biomimic materials with a wide range of applications could be opened up, such as multi-colour polymer coatings.

聚集诱导的具有新兴功能的二维蛋白质超分子纳米膜的发射

在空气/水界面或固体表面上以几分钟的时间首次实现了具有多种功能的二维蛋白质超分子纳米膜的聚集诱导发射（AIE）。溶菌酶，三（2-羧乙基）膦（TCEP）和9,10-二苯乙烯基蒽与两个铵基（DSAI）的混合物可快速合成相转变的溶菌酶（PTL）AIE纳米膜，涂料或油墨在室温下为中性水溶液。这些水性生物相容性DSAI @ PTL AIE材料的多功能性显示了一些潜在的应用，例如可食用物品或生物的抗菌和防伪。该策略将AIE的优势与2D生物聚合物超结构相结合，并提供了具有生物学功能和应用的环保界面材料。通过引入具有不同功能和发射特性的通用AIE分子，可以开发具有广泛应用的光学活性仿生材料，例如多色聚合物涂层。
