Outline of Final Research Achievements

The aim of this research was to understand the electrical interactions between biomolecules and 2-dimensional nanosheets by using peptides and layered materials such as grapehene and MoS2. First, we have focused on understanding the fundamentals of peptide self-assembly on nanomaterials. Especially, the self-assembly of graphite binding peptides has been investigated comprehensively. Then, the electrical interactions between peptides and nanosheets have been investigated using MoS2 FETs. The observations indicate that chemical doping by peptides on 2D nanosheets plays a significant role for the modification of the electrical and optical properties of 2D nanosheets.
