Dual-affinity peptides to generate dense surface coverages of nanoparticles

- Stable nanoparticles were created with the Flg-A3 fusion peptide as a ligand.
- Interactions of transition metal ions with Flg control aggregation of the nanoparticles in solution.
- The QBP1-A3 fusion peptide improves surface attachment of gold nanoparticles.
- Solution pre-aggregation of nanoparticles results in dense surface coverage.
