Synthesis, characterization, and antimicrobial activity of silver nanoparticles on poly(GMA‐co‐EGDMA) polymer support

Abstract

Poly(glycidyl methacrylate‐co‐ethylene glycol dimethacrylate) (poly(GMA‐co‐EGDMA) macroporous copolymer decorated with silver nanoparticles was prepared by a modification of poly(GMA‐co‐EGDMA) in the reaction with arginine, and consequent reduction of silver ions with amino groups. The mercury intrusion porosimetry, transmission electron microscopy, X‐ray diffraction, UV–vis reflection spectroscopy, and inductively coupled plasma atomic emission measurements were used to characterize obtained composite. The coordination of silver nanoparticles to the poly(GMA‐co‐EGDMA) copolymer was studied using infrared spectroscopy. Time dependence and concentration dependence of the antimicrobial efficiency of composite were tested against Gram‐negative bacteria Escherichia coli, Gram‐positive bacteria Staphylococcus aureus, and fungus Candida albicans. The composite ensured maximum reduction of both bacteria, while the fungi reduction reached satisfactory 96.8%. Preliminary antimicrobial efficiency measurements using laboratory flow setup indicated potential applicability of composite for wastewater treatment. POLYM.

Characterization of glycidyl methacrylate based magnetic nanocomposites

“…polymer core-magnetic shell, magnetic core-polymer shell and magnetic particles homogeneously distributed in the polymer bead [7]. Till now, synthesis of various polymer/magnetite nanocomposites was reported such as poly(methyl methacrylate)/Fe-oxide nanocomposites [1], poly(2-hydroxyethyl methacrylate)/Fe3O4 magnetic nanocomposites [8], poly(methyl methacrylate-co-acrylamide)/Fe2O3 [9], polyaniline/Fe3O4 [10], etc.. Glycidyl methacrylate (GMA) based copolymers have versatile applications due to the presence of epoxy groups, which offers numerous functionalization possibilities under mild reaction conditions [11].…”

Size‐dependent antibacterial properties of Ag nanoparticles supported by amino‐functionalized poly(GMA‐co‐EGDMA) polymer

“…Although, the ICP‐AES technique is not selective toward the chemical state of silver, having in mind thorough cleaning procedure of samples (see EXPERIMENTAL), we believe that the determined values correspond to the content of the metallic silver. The difference between specific surface area of polymer support and synthesized inorganic/organic hybrids is negligible, based on the reported data concerning the same polymer decorated with similar in size Ag NPs (5–10 nm) .…”

“…The poly(GMA‐ co ‐EGDMA) copolymer is frequently used as a starting material for various kinds of functionalization due to the presence of the reactive epoxy groups and macroporous structure. The thorough characterization of copolymer is already provided in literature . The average particle size, average pore radius, and specific surface area of copolymer were reported to be 30 μm, 137 nm, and 36 m 2 /g, respectively.…”

“…On the other hand, relatively little published data concerning composites based on poly(GMA‐ co ‐EGDMA) copolymer and natural materials can be found in the literature . Concerning inorganic/organic hybrids with noble metals component, only gold nanoparticles in the size range from 5 to 40 nm were attached to the surface of functionalized poly(glycidylmethacrylate‐ co ‐ethylene dimethacrylate) , and Ag NPs in the size range from 5 to 10 nm were attached to the surface of functionalized poly(GMA‐ co ‐EGDMA) copolymer .…”

Antimicrobial activity of silver nanoparticles supported by magnetite

“…On the other hand, when the concentration of Fe 3 O 4 /5‐ASA/Ag nanocomposite is twenty times higher (2.0 mg/mL), the percentage of E. coli reduction is about 5 times larger compared to S. aureus (65 and 12.5%, respectively). It should be emphasized that the performance of Ag NPs supported by functionalized Fe 3 O 4 with 5‐ASA is at the same level with the antimicrobial performance of Ag NPs attached to either textile fibers, or macroporous polymer support,, or inorganic support such as hydroxyapatite . Of course, the literature data, concerning the antibacterial performance of bare Ag particles without support with similar morphology to Ag NPs attached to functionalized Fe 3 O 4 with 5‐ASA have higher toxicity against bacterial species.…”
