Effects of biomineralization peptide topology on the structure and catalytic activity of Pd nanomaterials

Abstract

Highly branched, coral-like Pd nanostructures were formed using a biomineralization peptide conjugated to an oligomeric peptide that simultaneously controls the spatial orientation, arrangement and valency. The Pd nanocoral showed very high catalytic activity in the reduction of nitrophenol. The results highlight the importance of topological arrangement in nanostructure formation and catalytic activity.

Tetramer formation of tumor suppressor protein p53: Structure, function, and applications

“…To control the nanostructure formation of metals such as Pd, Au, and Pt, biomineralization peptides are useful . The control of valency and topological arrangement of Pd nanocoral was achieved through conjugating a biomineralization peptide with the p53TD peptide . Further, the Pd nanocoral obtained from this method showed very high catalytic activity in the reduction of nitrophenol.…”

Development of Core‐Shell Nanoparticle Drug Delivery Systems Based on Biomimetic Mineralization

“…Material synthesis using biomolecule-induced biomimetic mineralization offers many advantages such as benign reaction conditions, facet binding ability and specificity. [22] To date, several articles have reviewed the basic theories of biomimetic mineralization. [20a,23] An early review article in 2011 summarized different types of core-shell NPs, their properties, characterization, synthesis mechanisms and applications.…”

Effect of tryptophan residues on gold mineralization by a gold reducing peptide

“…For example, biomineralization (precipitation of inorganic compounds) systems can provide various inorganic precipitates following the addition of organic compounds such as proteins and peptides. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25] The reaction conditions for the production of inorganic compounds in biomineralization systems are much milder than those used in conventional methods. Therefore, such inorganic compounds formed by mineralization have a low environmental load and reduced energy consumption.…”
