Molybdenum disulfide (MoS₂) is a two-dimensional material promising for biosensing applications, and self-assembling peptides are useful as a non-destructive and simple method for surface functionalization to optimize its performance. However, the effects of peptide modification on the electronic and structural properties of MoS₂ have not yet been fully understood. In this study, we systematically analyzed Raman spectra by focusing on shifts in Raman peaks that reflect local doping and strain induced in MoS₂.
