Article Synopsis
- - Two-dimensional MoS nanosheets were created using an exfoliation technique with the help of peptides and sonication in water, achieving better results with uncapped peptides compared to capped ones.
- - Nanosheets produced with uncapped MoSBP1 are thinner and mostly single-layered, while capped versions tend to form multilayered structures of up to four layers.
- - Molecular dynamics simulations show that uncapped peptides are more effective at keeping gaps between nanosheets open longer, preventing them from re-stacking and aggregating, which explains the improved exfoliation efficiency observed in experiments.
The realization of multifunctional nanoparticle systems is essential to achieve highly efficient catalytic materials for specific applications; however, their production remains quite challenging. They are typically achieved through the incorporation of multiple inorganic components; however, incorporation of functionality could also be achieved at the organic ligand layer. In this work, we demonstrate the generation of multifunctional nanoparticle catalysts using peptide-based ligands for tandem catalytic functionality.

This could also unlock strategies for a wider uptake of graphene in bio-related applications. Graphene functionalisation can be achieved using peptides that specifically recognise the carbon-based material, resulting in persistent non-covalent adsorption without damaging the nanosheet.
