In situ depositing silver nanoclusters on silk fibroin fibers supports by a novel biotemplate redox technique at room temperature.

摘要: Evolvement of bioinspired approaches for the construction well-ordered nanostructures is a crucial intersection branches materials science and biotechnology. In this paper, floriated clusters silver nanocrystallites, which consist polycrystalline grains about 5 nm in diameter, have been successfully prepared on silk fibroin fibers (SFFs) through an situ biotemplate redox approach at room temperature. The reductive amino acid tyrosine SFFs mainly provided both reduction location functions under alkaline conditions could reduce Ag(I) ions to Ag(0). Finally, stable nanoclusters were generated SFF substrates. morphologies mostly attributed concentration nitrate solution as well special configurations structures macromolecules. A possible mechanism was explored intensively tyrosine-residue-based nanocrystal formation.
