“…Owing to their ultra-small size, good biocompatibility and intriguing physicochemical properties, noble metal clusters show significant promise in biolabeling/bioimaging, sensing, catalysis, and optoelectronic nanodevices [1-7]. In general, there are two pathways to synthesize these fascinating materials: chemical and biological methods.…”

“…Modification of oligoglycine with 1,10-phenanthroline stabilizes SN and facilitates the formation of sensor-and catalytically-active hybrid systems, while the presence of substituents in the structure of the heterocyclic modifier suppresses the capacity of oligoglycine to form hybrid composites [172]. The interaction of chromophore groups of amino acid fragments of peptides in silver clusters, which affects the optical properties of the hybrid systems [173], has found practical use in the preparation of hybrid biomarkers for the visualization of histidine-containing proteins in biochemical research [174]. Protein macromolecules containing tyrosine (2-amino-3-(4-hydroxyphenyl)propionic acid) fragments may reduce Ag + ions due to the phenolic OH groups according to the following scheme:…”

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
