Ornamentation of Triskelion Peptide Nanotori to Produce Gold Nanoparticle (AuNP)‐Embedded Peptide Nanobangles

Abstract

We report the formation of gold nanoparticle (AuNP)-biotinylated triskelion peptide hybrid nanostructures. These structures were created by using self-organization and mimicking strategies to develop AuNP-ornamented peptide nanobangles with predetermined properties on biocompatible surfaces. Such intelligent and fascinating nanomaterials can be used for several bio-nanotechnological applications.

“…Noble‐metal nanocrystals (NCs) are very important for applications in fields such as electrochemistry, electronics, magnetic storage, catalyst, and biotechnology . The properties of a metal NC are dependent on its morphology, including size and shape .…”

“…Noble-metal nanocrystals (NCs) are very important for applications in fields such as electrochemistry,e lectronics, magnetic storage, catalyst, andb iotechnology. [1][2][3][4][5][6][7][8][9][10][11][12][13] The properties of a metal NC are dependento ni ts morphology, including size and shape. [1][2][3][4][5][6] Therefore, many methods for the preparation of NCs with various shapes, such as nanoflowers, [14][15][16][17] nanocubes, [18][19][20][21] nanorods, [22][23][24] and nanowires, [25][26][27][28][29][30][31] with the desired properties have been reported.…”

Self‐assembly of a Sequence‐shuffled Short Peptide Amphiphile Triggered by Metal Ions into Terraced Nanodome‐like Structures

“…It is based on our past research interest for synthesizing fascinating nanostructures, we have strategically and deliberately designed a sequential series of peptide conjugates which can unveil new avenue of innovation in peptide nanotechnology. A short peptide amphiphile (sPA) was designed (Scheme ) which consists of three important segments; hydrophobic lipid chain (tail) and an aromatic dipeptide in the middle followed by a small non‐aromatic amino acid of varied hydrophilic nature (head).…”

“…The advances in peptide-based nanotechnology and its application in material science, is receiving tremendous attention due to extraordinary and high potential self-assemblingb ehaviour and therefore are highly demanded in nanotechnology. [1][2][3] Exploitation of significant short peptide conjugates may have great potentialt op roduce highly ordered assemblies with defined topologies, but the precise control still ac hallenging task to direct the peptide self organisationi nto desired functionality.V arious external stimuli such as light irradiation, [4,5] temperature, [6,7] solvent, [8,9] and pH variation, [10,11] electric and magnetic fields effect, [12] symmetry applications, [13,14] metal ions, [11,[15][16][17] chemicalm odification &c ovalentl inking of smallb iomolecules [18,19] and other factors have already been exploited to tune self assembly process.
