Biotin–avidin interaction triggers conversion of triskelion peptide nanotori into nanochains

Triskelion biotinylated peptide is self-assembled into nanotorus structures followed by dimerization and chain formation in the presence of avidin.

Biomimetic fabrication of biotinylated peptide nanostructures upon diatom scaffold; a plausible model for sustainable energy

This study demonstrates the interaction of biotin–Trp–Trp peptide with diatoms. Such interaction afforded unique nanoarray over the diatom frustules thus can be used as most parsimonious model for the production of renewable energy.
