This study is about how peptide sequences can control the assembly and growth of gold nanomaterials. Two cysteine-containing sequences, YYCYY and glutathione (GSH), have been newly identified as assembly motifs to control the resulting two-dimensional (2D) morphology. Cysteine interacts with gold ions and the gold surface to initiate nucleation and control growth. YYCYY forms a flat, 2D, gold-decorated film and GSH results in twisted, petal-like structures. By conducting a comparative study of these two sequences, the important role of peptide folding in the gold atom assembly process is investigated.

识别可以控制金纳米结构组装的肽序列†

这项研究是关于肽序列如何控制金纳米材料的组装和生长。最近已将两个含半胱氨酸的序列YYCYY和谷胱甘肽（GSH）识别为装配基序，以控制所得的二维（2D）形态。半胱氨酸与金离子和金表面相互作用，以启动成核作用并控制生长。YYCYY形成平坦的2D金色装饰膜，GSH形成扭曲的花瓣状结构。通过对这两个序列进行比较研究，研究了肽折叠在金原子组装过程中的重要作用。
