Self-Assembly of Tetra-Peptides on Surfaces of Two-Dimensional Materials

摘要

As the novel“bottom-up”strategy for fabricating nanomaterials, molecular self-assembly has attracted considerable attention worldwide. On one hand, two-dimensional (2D) materials such as graphite and molybdenum disulfide (MoS2) have been demonstrated as the platform for this self-assembly due to their unique electrical, optical properties, and atomically flat surfaces, etc. On the other hand, amphiphilic peptides with both of the hydrophobic and hydrophilic nature also have already been used as ideal building blocks for forming various sophisticated self-assembling materials with certain applications. Therefore, in order to functionalize the 2D material surface by peptides self-assembly, it is necessary for a deliberate understanding of the interaction between biomolecules and 2D substrate materials.
