“…-It has been known for a long time that ionic silver is a common antibacterial metal oxide against the pathogens including E. coli. 50,51 It is believed that silver particles bind into bacterial DNA content and prevent cell replication and interruption and inactivation of the electron transport chain of metabolic enzymes by binding to their sulfhydryl group, 52,53 according to Figure 2.…”

Surgical gloves provide a protective blockade for patients and members of the surgical team. Glove integrity is critical in an era of blood-borne pathogens. Therefore, the need for improved means for prevention and also gloving and appropriate hand hygiene in a hospital setting is ostensible. This perspective highlights the progress on antimicrobial surgical gloves in deducting the microbial passage after a glove puncture in a model of wound contamination. Moreover, traditional methods to avoid microbes in the hospital and various antimicrobial agents, such as metal ions and antiseptic dyes, are reviewed.

“…The capping or functionalization of inorganic materials adds new costs and operations for the preparation of inorganic polymer nanocomposites. The in situ technique is proposed for controlling the sizes, shapes and dispersion of various nanoparticles within supramolecular hydrogels . This method of preparation does not require any functionalization or external reducing/capping agents during the preparation of inorganic polymer composites.…”

In situ techniques have attracted great attention for the formation of nanomaterials with controlled sizes, shapes and dispersion within supramolecular hydrogels. In the present work, the doping of copper oxides onto magnetite nanoparticles into hydrogels based on sodium 2-acylamido-2-methylpropanesulfonate (AMPS) and N-isopropylacrylamide NIPAm copolymers was investigated. The contents, morphology and thermal stability of magnetite, cupreous oxide and doped copper oxides onto the magnetite nanoparticles were evaluated. The optimum conditions for removal the cationic dye methylene blue (MB), such as solution pH, concentration of adsorbents, contact time and stirring time, were determined to investigate the effect of MB concentrations on the removal efficiencies of the prepared adsorbents. The recyclability of the prepared AMPS/NIPAm composites for the removal of MB was examined for up to six cycles without changes in removal effectiveness.

“…The design and development of polymer-silver nanostructure composite materials have gained much attention in recent years due to their unique and versatile properties as nontoxic, environmentally friendly antibacterial materials, high surface area and high surface atom fraction [12][13][14][15]. These properties lead to potential applications in the field of biomedical, pharmaceutical, tissue engineering, food packaging, and catalysis applications, as well as water treatment, optical and electrical usages [16][17][18].…”

A series of acrylamide (AAm) based hydrogels containing acrylic acid (AAc), 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) and vinyl imidazole (VI) comonomers were prepared by free radical polymerization. Silver nanoparticles were loaded to hydrogels systems via in situ reduction of silver nitrate in the presence of sodium borohydride as a reducing agent. The synthesized hydrogels and their composites were characterized using FT-IR, SEM, EDX and EDX-Mapping. The antimicrobial activity of hydrogel-silver composite was determined by using well agar and broth dilution tests. In the first stage, four different hydrogel-silver composites were evaluated against six different microorganisms using the well agar technique. The most effective hydrogel-silver composite among all tested was poly (AAm-co-VI-co-AMPS)-Ag, while the most sensitive and resistant microorganisms among all tested were S. cerevisiae and S. aureus respectively. Poly (AAm-co-VI-co-AMPS)-Ag composite was used in modeling the inhibition kinetic of E.coli. The present study displays that hydrogel-silver composite has considerable antimicrobial activity, which deserves further investigation for use in clinic application and industrial processing.2 Graphical Abstract KEYWORDS: Acrylamide based hydrogels, hydrogel-silver composites, antimicrobial activity, inhibition kinetic.
