As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting proof before it is published in its final form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. AgNPs not only maintains more than 80% of cell activity to RPMI2650, but also possesses more than 80% of antibacterial function to S. aureus and 100% of antibacterial function to E.coli. Therefore, 5 ppm of AgNPs might be considered as a promising antibacterial agent for treating CRS.

Fabrication and characterization of biodegradable Mg-Zn-Y-Nd-Ag alloy: Microstructure, mechanical properties, corrosion behavior and antibacterial activities

“…In addition to the formation of indissolvable substance with some ions in the bacteria solution, part of silver ions also plays an important role in sterilization. Silver ions in antibacterial material active oxygen to produce hydroxy and O 2− , and bacterial metabolic disturbance might inhibit or kill bacteria owning to the DNA molecular damaged by O 2− [ 19 , 20 ] (see Fig. 13 ).…”

Application of Eco-Friendly Waterborne Polyurethane Composite Coating Incorporated with Nano Cellulose Crystalline and Silver Nano Particles on Wood Antibacterial Board

“…Meanwhile, AgNPs with a size less than 15 nm are well known to have efficient antibacterial activity because they are able to penetrate inside the bacteria and cause further damages, possibly by interacting with sulfur-and phosphorus-containing moieties of DNA. However, when the particle size is more than 15 nm, its bactericidal effect is significantly reduced, or there is even no bactericidal effect [18,19]. From the TEM diagram of AgNPs, it can be seen that when the Ag content is 1%, 3%, 5% (Figure 6a-c), respectively, the particle size of AgNPs is less than or close to 15 nm.…”

“…The complexes have good antibacterial properties against gram-negative Escherichia coli (E. coli) and gram-positive Staphylococcus aureus. A mixture of nanocellulose and AgNPs nanocomposites not only exhibit good antibacterial function, but also improve mechanical properties, and thus they can be used in the field of active packaging films, coatings and adhesives [19].At present, although there are many studies on the introduction of AgNPs and nanocellulose whiskers, most of them are aimed at the modification of the coatings themselves, and there is no specific application, especially in wood protection. For coatings used in different substrates, their performance and process will be very different.…”

Facile synthesis of Silver nanoparticles with medicinal grass and its biological assessment

“…Among the various bacterial strains, the SS-Ag NPs showed enhanced antimicrobial activity against K. pneumoniae ( figure 8b) due to the variations in cell structure, diffusion rate, metabolism and interaction of the nanoparticles with the microorganisms [53]. [57]. However, after 48 hours, the percentage of cell viability was increased up to 135 % above the control in lower concentrations [58,59].…”
