“…[ 150 ] Silver and silver oxide (Ag 2 O) nanoparticles have diverse antibacterial applications in dentistry, [ 105,111,151 ] as scaffolds for tissue engineering [ 152,153 ] and as wound healing materials. [ 154,155 ] They have also been used as antimicrobial materials in other industries including food packaging, [ 156,157 ] drinking water disinfection, [ 158 ] and textile manufacturing. [ 159 ] Because of their vast range of applications, it is not possible to include all applications here and only some examples are reviewed.…”

Microbial colonization on material surfaces is ubiquitous. Biofilms derived from surface-colonized microbes pose serious problems to the society from both an economical perspective and a health concern. Incorporation of antimicrobial nanocompounds within or on the surface of materials, or by coatings, to prevent microbial adhesion or kill the microorganisms after their attachment to biofilms, represents an important strategy in an increasingly challenging field. Over the last decade, many studies have been devoted to preparing meta-based nanomaterials that possess antibacterial, antiviral, and antifungal activities to combat pathogen-related diseases. Herein, an overview on the state-of-the-art antimicrobial nanosized metal-based compounds is provided, including metal and metal oxide nanoparticles as well as transition metal nanosheets. The antimicrobial mechanism of these nanostructures and their biomedical applications such as catheters, implants, medical delivery systems, tissue engineering, and dentistry are discussed. Their properties as well as potential caveats such as cytotoxicity, diminishing efficacy, and induction of antimicrobial resistance of materials incorporating these nanostructures are reviewed to provide a backdrop for future research.

“…The formation of increased size and different shape is due to the adsorption of silver on the surface of chitosan nanoparticles, which leads to form a chelate ring like structure. Kumar et al [26] stated that the concentration, nature of stabilizing and reducing agents influences the size and shape of silver nanoparticles. The average size revealed by TEM micrographs is smaller for both chitosan nanoparticles and Chi-Ag-NPs as compared to that measured by Zeta sizer.…”

Metal-based nanoparticles with potential antioxidant and antimicrobial properties have led to their incorporation of biomaterials for human health care importance. The present investigation is to study on the silver nanoparticles grafted chitosan (Chi-Ag-NPs) composite materials due to their potential applications. Chi-Ag-NPs were synthesized by chemical reduction of silver nitrate salts and biodegradable chitosan. The obtained Chi-Ag-NPs were characterised for Fouriertransform infrared spectroscopy (FTIR), scanning electron microscope (SEM), Transmission electron microscopy (TEM), X-ray powder diffraction, antioxidant and antibacterial properties. UV-visible spectra showed the configuration proficiency of Ag-NPs and chitosan. FTIR spectra indicated that the functional groups of chitosan have particular interactions with Ag-NPs. Particle size and TEM analyses showed that Chi-Ag-NPs were equivalently dispersed in matrix with an average size of 10-230 nm. The surface morphological structures of chitosan has played important role in influencing the adsorption of Ag-NPs. Chi-Ag-NPs were tested for their bioactive properties and results exhibited higher antioxidant and antibacterial activities by the addition of Ag-NPs. Chi-Ag-NPs composites were non-toxic to L929 fibroblast cells. The present investigation suggested that chitosan will be a good source for the preparation of bionanocomposite materials and also could be useful in different industrial and biomedical applications.

“…The resulting nanocomposite inhibited the growth of S. aureus, E. coli, and C. albicans. Kumar et al (2018) developed an innovative hybrid food film composed of two commonly used biopolymers, chitosan and gelatin, with the addition of Ag-NPs. The researchers evaluated the effectiveness of this nanocomposite in extending the shelf life of red grapes.…”
