“…The effect of 40nm silver nanoparticles on the photocycle of bR has been studied using visible spectroscopy by Adamov et al [67]. They reported that for bR modified Ag NPs, the plasmon resonance peak blue shifts (from 410 to 402 nm) but the position of the bacteriorhodopsin band remains unchanged (568 nm).…”

“…In addition, the intensity of the absorption band at 400-410 nm was increased, with increasing the bR concentration. Therefore, it can be expected that nanoparticles affect the bR photocycle [67].…”

“…The interaction of the amino-containing structural units in the protein, bacteriorhodopsin (bR), namely, cysteine, arginine, lysine (polylysine) with SN [165,166] leads to a shift of the PR band toward longer wavelengths (Dl depends on the structure of the amino-containing spacer) along with an increase in the intensity of this band by 4%-26%, which permits us to use these composites as sensitizers for photochemical reactions [167]. Detailed studies of such systems have shown that the presence of NH 2 [61,168] or CO 2 H groups [169] in protein macromolecules is conducive for the formation of hybrid structure without the introduction of additional reactive compatibilizers.…”

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
