“…3), show that PSP had a wide and strong absorption around 3386 cm −1 , which was caused by the stretching vibration absorption of ‐NH and ‐OH 33‐35 . Absorption peaks were also noticed at 2937 cm −1 , caused by methyl antisymmetric stretching vibration 36 . The strong absorption at 1654 cm −1 appeared due to the stretching vibration of ‐CONH, 37, 38 and the peak at 1415 cm −1 appeared owing to the symmetric stretch absorption of ‐COO‐ 39 .…”

“…All the peaks were blue-shifted to varying degrees, suggesting that the functional groups corresponding to these peaks in PSP might be conjugated with SeNPs, and they were involved in the stabilization process of PSP-SeNPs. 29,36 The spectrum also indicates that Se interacts with the -CONH, -COO-and C O groups of PSP. 40 The Se O and Se N bond interactions formed between PSP and SeNPs might therefore help in forming the highly stable and well-dispersed spherical structure of PSP-SeNPs.…”

BACKGROUND: Compared with traditional inorganic and organic selenium compounds, nano-selenium exhibited higher biological safety and nutritional potency. However, the biological efficacy of nano-selenium has not been comprehensively and accurately evaluated due to its dispersion instability. RESULTS: In this study, novel selenium nanoparticles (SeNPs) with high dispersion stability were successfully prepared using a polysaccharide-protein complex (PSP) as the capping agent. This was isolated from abalone viscera. The average particle size and zeta potential of polysaccharide-protein complex selenium nanoparticles (PSP-SeNPs) were 63.33 nm, and −37.1 mV, respectively. The SeNPs were firmly capped by PSP through Se O and Se N bonds, as demonstrated by X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy, and transmission electron microscopy. Due to this capping, the dispersion of PSP-SeNPs remained stable for 12 months at 4°C, as evidenced by visual inspection and multiple light scattering. Furthermore, PSP-SeNPs imparted an excellent growth-promoting effect on tilapia. The FBW, WGR, and SGR values of tilapia juveniles fed with PSP-SeNPs supplemented diets (0.5-4.5 mg/kg) were significantly higher than those of the control (P < 0.05). A weight gain rate of 4.1%-43.4% and specific growth rate of 0.15%-1.74% were obtained in tilapia during 45day feeding. CONCLUSIONS: The use of marine viscera polysaccharides is a promising, green method for the synthesis of selenium nanoparticles. There are good opportunities for the application of the synthesized PSP-SeNPs in the life sciences.

“…The deposition of SN on the surface of poly(St) microspheres modified with ClSO 3 H gave nanocomposites, in which the SN are stabilized due to their reaction with the SO 3 H groups of the polymer matrix [92]. The photochemical reduction of Ag + (or Pd 2+ ) ions in the presence of particles of poly(St) or the copolymer of St and IPAAM, containing poly(methylphenylsilane), leads to the deposition of SN on the polymer surface and formation of hybrid catalysts for the reduction of 4NT, whose activity decreases with increasing size of the metal particles [93,94].…”

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
