“…Here, the reduction of the palladium precursor to Pd(0) is attributed to the presence of Cys residues along insulin fibril surfaces, as indicated by Kurouski et al with tip-enhanced Raman spectroscopy (TERS) [35]. A similar phenomenon where palladium precursors self-mineralized on Cys mutant TMV was also reported by several other research groups [22,36]. Very recently, Sobjerg et al also demonstrated the bacterial synthesis of Pd(0) [37].…”

“…6,[37][38] Moreover, many groups have shown that highly ordered protein assemblies with larger dimensions, like viral particles, are ideal functional scaffolds for the synthesis and organization of NP of different sizes and chemical compositions. 39 Measurements of nanoparticle diameter from TEM micrographs (Figure 1b) demonstrated a correlation of a decrease of mean nanoparticle size as the MPS content increased in the reaction solution ( it is possible to obtain stable and soluble gold clusters (1.5 to 5.2 nm) in organic solvents by using 1-dodecanethiol as a capping agent. 40 The same group synthesized water-soluble gold clusters of 1.8-3.9 nm using tiopronin.…”

Biomolecules are advantageous scaffolds for the synthesis and ordering of metallic nanoparticles. Rotavirus VP6 nanotubes possess intrinsic affinity to metal ions, a property that has been exploited to synthesize gold nanoparticles over them. The resulting nanobiomaterials have unique properties useful for novel applications. However, the formed nanobiomaterials lack of colloidal stability and flocculate, limiting their functionality. Here we demonstrate that it is possible to synthesize thiol-protected gold nanoparticles over VP6 nanotubes, which resulted in soluble nanobiomaterials. With this strategy, it was possible to modulate the size, colloidal stability, and surface plasmon resonance of the synthesized nanoparticles by controlling the content of the thiolated ligands. Two types of water-soluble ligands were tested, a small linear ligand, sodium 3-mercapto-1-propanesulfonate (MPS), and a bulky ligand, 5-mercaptopentyl β-D-glucopyranoside (GlcC5SH). The synthesized nanobiomaterials had a higher stability in suspension, as determined by Z-potential measurements. To the extent of our knowledge, this is the first time that a rational strategy is developed to modulate the particular properties of metal nanoparticles in situ synthesized over a protein bioscaffold through thiol coating, achieving a high spatial and structural organization of nanoparticles in a single integrative hybrid structure.

“…Attention is now turning toward hybrid systems derived from SN and biomacromolecules capable of self-assembly to give nanotubes [176,177], virus-like particles [178], and viruses [179]. Filling the cavities of nanotubes formed upon the self-assembly of peptide molecules possessing specific structure with silver permits us to obtain composites with unique electrical conductance and electromagnetic properties [176,177].…”

The major methods for the preparation of silver-containing polymer composite nanosystems and the formation of their hybrid structure are examined. Special attention is focused on a new class of silver-containing hybrid systems, namely, organic-inorganic coordination polymers, obtained by the self-assembly of silver complexes. The effect of intercomponent interaction on the structure and properties of these hybrid composites was examined.The creation of new improved materials is an important goal of modern chemistry and materials science. Polymer composites with hybrid structure are among such materials and hold interest since they display a combination of properties characteristic for each of the inorganic and organic components [1-3] and, in some cases, unique properties related to the specific nature of their structure [4]. From a modern viewpoint, hybrid organic-inorganic materials are formed by the combination of components, differing in their chemical nature, on a molecular or nano level through formation of chemical bonds ((non)covalent bonds, hydrogen bonding, and donor-acceptor bonds) or weaker physical bonds (van der Waals and electrostatic interactions) [5]. Special attention is given to the stability of the nanodispersed components due to interaction between the nanophase and various stabilizers [6]. The interest in silver-containing hybrid polymer composite materials, including nanocomposites, which, by their very nature, are a priori hybrid systems, is attributed to a set of properties of the matrix itself, which often possesses hybrid structure, properties of silver in ionic and nanodispersed forms, and new properties related to the appearance of hybrid silver-polymer structures [7,8]. Special interest is presently found in bionanocomposites derived from biopolymers and silver nanoparticles (SN), which display specific physicochemical properties, in particular, electrochemical, photochemical, and catalytic properties highly dependent on the dimensions and polydispersion of the nanophase [9, 10] as well as biological activity due to the ionization of the metal atoms in the presence of H 2 O/O 2 and the interaction between the SN surface and functional groups of the various biomolecules [11].In light of the important role of the polymer matrix in formation of the major structural characteristics and properties of silver-containing hybrid systems, we should classify these materials according to their chemical structure.Composites with Silver Nanoparticles (SN) Dispersed in a Polymer Matrix with Hybrid Structure. The major distinguishing feature of such materials is the prior synthesis of the hybrid polymer matrix obtained due to the formation of chemical bonds between the organic and inorganic components with subsequent introduction of SN into the system. The synthesis of the SN may be either in situ or ex situ. 740040-5760/15/5102-0074
