Our group utilizes peptides to create sustainable materials for electronic, energy, and biomedical applications. We develop peptide-based templates for controlled deposition of nanocrystalline inorganic films with tailored electronic properties. Additionally, we explore peptide self-assembly to construct functional nanostructures with desired properties. Our research combines modularity, biocompatibility, and biodegradability to advance electronic technologies, energy systems, and biomedical applications.
