“…The results of XRD are in agreement with other studies which reported that a strong reflection was exhibited around 33°and 40°of the silver nanoparticles (Govindan et al 2012;Hajji et al 2019;Suteewong et al 2018). Therefore, this gives a clear evidence for the preparation of Ch-AgNPs in the current study.…”

Background: In recent years, the development of efficient and green route to synthesis metal nanoparticles has gained considerable attention in various areas of nanotechnology. Among metal nanoparticles, silver nanoparticles (AgNPs) have attracted much interest because of their potential antimicrobial agents and they are widely applied in many biological and medical fields. With respect to Ag-based nanocomposites, chitosan-silver nanoparticles (Ch-AgNPs) represent an emerging group of bio-nanostructured hybrid materials due to their biocompatibility and biodegradability. Ch is considered a non-toxic biopolymer, as well as its antimicrobial and antifungal activities against a wide range of microorganisms. Methods: Colloidal AgNPs were prepared by chemical reduction of silver ions in the presence of Ch giving Ch-AgNPs. Physiochemical characterizations were determined by scanning electron microscopy (SEM), X-ray diffraction (XRD), and zeta potential. In vitro antibacterial activity was evaluated against Escherichia coli and Salmonella typhimurium using nutrient agar dilution method. The in vivo antibacterial activity was also tested against E. coli in minced meat under aerobic conditions at 4°C for 10 days. In addition, different biochemical parameters were determined in minced meat samples. Results: The colloidal AgNPs formed in situ by chemical reduction of Ag ions in the presence of Ch and showed a good stability. SEM and XRD confirmed the formation of nanoparticles. Zeta potential value was decreased by increase the ratio of Ag and was found to be − 0.225, − 0.193, and − 0.0695 mV for Ag ratio 0.1, 0.2, and 0.35, respectively. The in vitro antibacterial activity of Ch and Ch-AgNPs against E. coli and S. typhimurium reveal that the E. coli was more susceptible to these products than S. typhimurium and Ch-AgNPs have more influence with increasing of the silver concentrations. The in vivo antibacterial activity against E. coli in minced meat samples showed that the effect of Ch-AgNPs was a concentration dependent and greater compared with either controls or Ch alone. Conclusions: The results suggest that Ch-AgNPs could be used in food preservation as antimicrobial agents and for shelf-life extension. However, further toxicological studies on mammals are needed.

“…This study showed that these types of coatings can be applied to various soft substrates in different biomedical applications. The deposition of PMMA/chitosan-silver (PMMA/AgNPs-CS) nanoparticles on a soft rubber substrate was achieved by immersion method which improved antibacterial activity [56]. Positively charged AgNPs-CS (38 nm) was heterocoagulated on the negatively charged PMMA cores (496 nm) to produce PMMA/AgNPs-CS, which was then deposited on the rubber substrate.…”

“…A plethora of studies focused on overcoming the disadvantages of PMMA denture resins. Previous research has reported the use of several fillers to reinforce the PMMA structures, such as: zirconium oxide, rubber derivatives, nanoclay, glass fiber and graphene [22,23,24,25]. Data showed that the presence of the high-elastic modulus graphene in a low modulus polymeric matrix can lead to important reinforcement; therefore, many studies have approached the mechanical properties of graphene nanocomposites [26].…”

The clinical performances of dental materials depend on their mechanical profiles, determining their long-term deformation and wear resistance. This paper describes a study on the mechanical properties, water absorption and morphological properties of a polymethyl methacrylate (PMMA) resin enriched with graphene-silver nanoparticles (Gr-Ag). Two different concentrations—1 and 2 wt.%—of Gr-Ag were loaded into the PMMA material. For the mechanical characterization, the compression behavior, flexural strength and tensile strength were evaluated. Optical microscopy in polarized light and scanning electron microscopy were used for filler analysis. The filler addition led to an improvement in all mechanical properties, with slight changes being derived from the filler content variation. Gr-Ag use led to an increase in the applied maximum loads. Moreover, 1 wt.% Gr-Ag determined an increase of 174% in the modulus of rupture, which indicates high flexibility.
