Radiolytic synthesis and characterization of Ag-PVA nanocomposites

Mechanical properties and in vitro characterization of polyvinyl alcohol-nano-silver hydrogel wound dressings

“…As a consequence, a therapeutic window is established, where the silver is incorporated within a range that inhibits bacteria without reaching levels toxic to human cells [23]. Studies on the use of gamma radiation in PVAAg systems with the final goal of obtaining nanoparticles [24,25], and studies on PVA blends that were gamma-irradiated and loaded with silver to be used in wound healing have been developed recently [9,26]. PVA hydrogels loaded with a controlled concentration of silver could combine the hydrogel property of keeping a moisturized environment, that stimulates healing, with the silver (antibiotic) effect of inhibiting or killing the bacteria on site and, consequently, avoiding infection.…”

Synthesis and characterization of AgBr nanocomposites by templated amphiphilic comb polymer

“…There has been a growing interest in the synthesis and characterization of nanoparticles, nanocomposites, and nanostructured materials over the last decades [1][2][3][4][5]. Some nanomaterials have exhibited attractive size-related optical, electrical, mechanical and transport properties, and as such they are considered to be intriguing functional materials with potential applications in various fields such as magnetic resonance imaging (MRI) [6], electrochemistry [7] and photoluminescence [8].…”

Preparation and characterization of silver-modified poly(vinyl alcohol)/polyethyleneimine hybrids as a chemical and biological protective material

“…A large number of synthetic procedures have been employed in order to synthesize silver nanoparticles and/or nanocomposites. Usage of strong reducing agents in water [8,9] and organic solvents [10], laser ablation [11], sonochemical treatment [12], UV irradiation [13] and gamma irradiation [14] have been applied for synthesis of silver nanoparticles, while polymers [15] and membranes [16] have been used as matrices for preparation of nanocomposites. If silver is immobilized on porous hosts or polymers matrices, the release time of silver ions can be delayed, so that silver-supporting materials will have great potential for use in this application [17].…”
