Outline of Final Research Achievements

The aim of this work was to establish a sensing interface consisting of 2-dimensional nanomaterials and biomolecules. We have formed a new type of interface using self-assembled peptides on MoS2 (2D nanomaterial) and have succeeded to obtain fundamental information about its physical properties by using optical and electrical measurements. The properties of MoS2 is sensitive to the condition of interface such as ion concentration, pH, and species of ions. It is also modified by the self-assembled peptides. These results open a new door for an establishment of bio-nano interface based on designed peptide toward more functional bio-active interface.
