“…22,23 Most popular methods employed for encapsulation include emulsion polymerization, surfactant-free emulsion polymerization, emulsion-like polymerization, suspension polymerization, and dispersion polymerization. Among metal/polymer composites, silver composites have found important applications in material technologies like optical materials, 24 catalytic systems, antibacterial materials, 25,26 chemical nanosensors, and surface-enhanced Raman scattering (SERS). 27 However, the most significant challenge encountered in preparing silver/polymer nanoparticle encapsulation is that the nanoparticles cannot be dispersed in polymer matrix at the nano level by conventional techniques because the surface energies of tiny silver particles are very high, and these particles tend to agglomerate during mixing.…”

New silver nanoparticle (AgNP)-loaded amino acid based hydrogels were synthesized successfully from poly (vinyl alcohol) (PVA) and poly(acryl amide-co-acryloyl phenyl alanine) (PAA) by redox polymerization. The formation of AgNP in hydrogels was confirmed by using a UV-Vis spectrophotometer and XRD. The structure and morphology of silver nanocomposite hydrogels were studied by using a scanning electron microscopy (SEM), which demonstrated scattered nanoparticles, ca. 10-20 nm. Thermogravimetric analysis revealed large differences of weight loss (i.e., 48%) between the prestine hydrogel and silver nanocomposite. The antibacterial studies of AgNP-loaded PAA (Ag-PAA) hydrogels was evaluated against Escherichia coli (Gram-negative) and Staphylococcus aureus (Gram-positive) bacteria. These Ag-PAA hydrogels showed significant activities against all the test bacteria. Newly developed hydrogels could be used for medical applications, such as artificial burn dressings.

“…When a sample solution such as glucose was applied to the surface of this optical enzyme biosensor, the interparticle distances of the silver nanoparticle present in the stimuliresponsive hydrogel were increased, and thus the absorbance strength of the LSPR was decreased. The concentration of glucose is determined by using the optical enzyme biosensors [18].…”

Abstract:-Nanotechnology is an emerging field with diverse applications in pharmacy, medicine, industries and environments. Among nanosized particles, the inorganic nanoparticles posses unique physical and chemical properties. These nanoparticles and their composites are useful for the wide range of applications. This review aims to provide a consolidated assessment of silver nanoparticle and silver nanocomposites in various fields. Among nanoparticles, silver nanoparticle exhibits antimicrobial activities and prominent in diverse applications. The nanosilver composites by coating of chemical material, agricultural residues, other matrices etc., have been used for the development of new materials that could be conveniently used in house cleaning solutions, fabric cleaners, wound bandages, paints, ornamental glasses, electronics circuits, fridge, washing machines and cosmetics, etc., Similarly, silver nanoparticle can also be functionalized with various groups of commercial adsorbents and agricultural residues to increase their affinity towards target compounds and used as a selective sorbents for metal ions and anions.

“…In addition, there are various studies on the use of hydrogel-silver nanocomposites as wound dressings (Hong, 2007;Rujitanaroj et al, 2008), for biologic labeling (Xu et al, 2012) and drug delivery (Xiang and Chen, 2007), and as biosensors (Endo et al, 2008) and photonic crystals (Xu et al, 2003). There are also different articles about polymeric membranes containing silver salts (Pollo et al, 2012) and, MgO nanoparticles as antibacterial agent (Tang et al, 2012;Tang et al, 2014.…”

-In this study, copolymeric and terpolymeric hydrogel-silver nanocomposites based on poly(acrylamideco-itaconic acid), poly(acrylic acid-co-itaconic acid) and poly(acrylic acid-co-acrylamide-co-itaconic acid) were synthesized by free-radical polymerization. These nanocomposites were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Scanning Electron Microscopy (SEM), UV-Visible Spectrophotometry (UVVis) and X-Ray Diffraction (XRD) analysis, as well as their swelling behaviors. In addition, antibacterial properties of these hydrogel-silver nanocomposites were investigated against Pseudomonas aeruginosa. Acrylic-based hydrogel-silver nanocomposites demonstrated antibacterial activity against Gram-negative bacteria. These hydrogel-silver nanocomposites can be used as antibacterial material in the medical field.
