Abstract
The substantial increase in multidrug-resistant (MDR) pathogenic bacteria is a major threat to global health. Recently, the Centers for Disease Control and Prevention reported possibilities of greater deaths due to bacterial infections than cancer. Nanomaterials, especially small-sized (size ≤10 nm) silver nanoparticles (AgNPs), can be employed to combat these deadly bacterial diseases. However, high reactivity, instability, susceptibility to fast oxidation, and cytotoxicity remain crucial shortcomings for their uptake and clinical application. In this review, we discuss various AgNPs-based approaches to eradicate bacterial infections and provide comprehensive mechanistic insights and recent advances in antibacterial activity, antibiofilm activity, and cytotoxicity (both in vitro and in vivo) of AgNPs. The mechanistic of antimicrobial activity involves four steps: (i) adhesion of AgNPs to cell wall/membrane and its disruption; (ii) intracellular penetration and damage; (iii) oxidative stress; and (iv) modulation of signal transduction pathways. Numerous factors affecting the bactericidal activity of AgNPs such as shape, size, crystallinity, pH, and surface coating/charge have also been described in detail. The review also sheds light on antimicrobial photodynamic therapy and the role of AgNPs versus Ag+ ions release in bactericidal activities. In addition, different methods of synthesis of AgNPs have been discussed in brief.

Abstract
We used an in situ chemical oxidation method to prepare a new composite of silver nanoparticles (AgNPs) with polypyrrole (PPy), whose properties were optimized through a 23-factorial design of the synthesis conditions. The successful formation of the AgNPs/PPy composite was confirmed by UV-Visible and FTIR spectroscopies. Transmission electron microscopy revealed the presence of AgNPs smaller than 100 nm, dispersed into the PPy matrix. This hybrid composite exhibits a blue fluorescence emission after excitation in the ultraviolet region. In MTT assays, the AgNPs/PPy composite exhibited low cytotoxicity toward non-tumoral cell lines (fibroblast, Vero, and macrophages) and selectively inhibited the viability of HeLa cells. The AgNPs/PPy composite induces ultrastructural changes in HeLa cells that are consistent with the noticeable selectivity exhibited toward them when compared to its action against non-tumoral cell lineages. Also, the AgNPs/PPy exhibited a hemolytic activity below 14% for all blood groups tested, at concentrations up to 125 μg/mL. These results suggest that the AgNPs/PPy composite has a promising potential for use as an antitumoral agent.

Abstract
Cationic glycopolymers with structures similar to those of typical poly(ionic liquid)s (PILs) were synthesized via the quaternization reaction of poly(4-vinyl pyridine) with halogen-functionalized d-mannose and tetraphenylethylene units. Such postpolymerization modification provided PILs with aggregation-induced emission effect as well as specific carbohydrate-protein recognition with lectins such as concanavalin A. The interactions between cationic glycopolymers and different microorganisms, including Gram-positive Staphylococcus aureus and Gram-negative Escherichia coli, were used for the killing, imaging, and detection of bacteria. Besides, these sugar-containing PILs showed a relatively low hemolysis rate due to the presence of saccharide units, which may have potential application in the field of biomaterials.

Abstract
Otitis media, commonly known as middle ear inflammation, is among one of the most common maladies and results in significant morbidity such as loss of hearing. In view of the bacteria invasion such as Staphylococcus aureus causes the majority forms of otitis media, drug treatment generally uses antibacterial by topical or systematic approach. However, the effectiveness of antibacterial is diminishing because of the rapid emergence of antibiotic-resistant bacterial strains. Here, we designed and fabricated a silver nanoparticle (AgNPs)-based multicomponent hybrid nanocomposite termed as TSIIA @ CS/Lys @ AgNPs, which was comprised of a AgNPs core, a chitosan (CS) or lysozyme (Lys) middle layer, and a Tanshinone IIA (TSIIA) inclusion outlayer. Coating of CS or Lys to AgNPs through electrostatic interaction probably produced a core-shell nanocomplex resembling the endocarp of walnut. This design could reduce the dosage of AgNPs while maintaining antibacterial activity possibly due to the favorable interactions between nanocomplex and bacteria. The deposition of Chinese herb active component TSIIA by inclusion complexation formed the out layer of hybrid nanocomposite towards an improved antibacterial performance, which showed a therapeutic effect against acute otitis media of guinea pig comparable to the clinical commercial-used ofloxacin administrated by injection. The hybrid nanocomposite, when dispersed in poly (lactic-co-glycolic acid)/N-methyl-2-pyrrolidone (PLGA/NMP) solution as an in-situ organogel, not only maintained the therapeutic effectiveness, but also possessed the advantage of lower injection frequency compared with solution formulation. In addition, no obvious toxicity to the basilar membrane and epithelia tissue was observed after the healthy guinea pigs were treated with hybrid nanocomposite or organogel. This study provides a promising strategy to develop hybrid nanocomposite with enhanced antibacterial efficacy and also opens a new way for the establishment of efficient therapeutic systems with reduced administration frequency as substitute of antibiotics to treat otitis media.

Abstract
Designing cationic nano-antimicrobial is a promising solution for combating drug resistant microbes. In this work, hydrophilic cationic copolymer was applied for the surface functionalization of nanodiamonds (NDs) aiming at developing a highly membrane-active nano-antibacterial agent with satisfactory selectivity. As a result, after functionalization, the increased repulsive forces within NDs and interaction with solvent molecular network made the heavily aggregated pristine NDs break down into tiny nanoparticles with particle size ranging from 10 to 100 nm. The improved hydrophilicity and enlarged surface area endowed QND-H5 and QND-H10 a powerful bactericidal capability toward both of Gram-negative Escherichia coli (E. coli) and Gram-positive Staphylococcus aureus (S. aureus). In the further bactericidal assessment, it was also demonstrated that the formation of hydrogen bonding between the 2-hydroxyethyl methacrylate (HEMA) side chains and lipid head groups of bacterial membrane also contributed to the enhanced bactericidal ability. Field emission scanning electron microscopy analysis confirmed that as-prepared nano-hybrid acted bactericidal ability via physical nature of outer membrane and cytoplasmic membrane-separating destruction mechanism toward E. coli, which may derive from the hydrogen bonding ability, making them more effective toward bacterial. More importantly, it was found that with just 10% of HEMA, QND-H10 displayed good selectivity toward bacteria over mammalian cells as shown by the high HC50 values with relatively low MIC values, suggesting the great potential application in medical fields. These results indicate that hydrogen bonding is an important element to achieve the desired high antibacterial activity and selectivity, particularly when cationic nano-antibacterial agents are required for medical application.

Abstract
To explore the structure-activity relationship of membrane-targeting cationic ligands on a silver nanoparticle surface in an antibiotic-resistant antibacterial and antibiofilm activity assay, a series of functionalized silver nanocomposites were synthesized. Tuning the structural configuration, molecular weight, and side-chain length of the cationic ligands on the nanoparticle surface provided silver nanocomposites with effective antibacterial activity against both antibiotic-resistant Gram-negative and Gram-positive bacteria, including bacterial biofilms. These silver nanocomposites did not trigger hemolytic activity. Significantly, the bacteria did not develop resistance to the obtained nanocomposites even after 30 generations. A study of the antibacterial mechanism confirmed that these nanocomposites could irreversibly disrupt the membrane structure of bacteria and effectively inhibit intracellular enzyme activity, ultimately leading to bacterial death. The silver nanocomposites (64 μg/mL) could eradicate 80% of an established antibiotic-resistant bacterial biofilm. The strong structure-activity relationship toward antibacterial and antibiofilm activity suggests that variations in the conformational property of the functional ligand could be valuable in the discovery of new nano-antibacterial agents for treating pathogenic bacterial infections.

Abstract
With the increased prevalence of antibiotic-resistant bacteria infections, there is a pressed need for innovative antimicrobial agent. Here, we report a benign ε-polylysine/silver nanoparticle nanocomposite (EPL-g-butyl@AgNPs) with polyvalent and synergistic antibacterial effects. EPL-g-butyl@AgNPs exhibited good stability in aqueous solution and effective antibacterial activity against both Gram-negative (P. aeruginosa) and Gram-positive (S. aureus) bacteria without emergence of bacterial resistance. Importantly, the nanocomposites eradicated the antibiotic-resistant bacteria without toxicity to mammalian cells. Analysis of the antibacterial mechanism confirmed that the nanocomposites adhered to the bacterial surface, irreversibly disrupted the membrane structure of the bacteria, subsequently penetrated cells, and effectively inhibited protein activity, which ultimately led to bacteria apoptosis. Notably, the nanocomposites modulated the relative level of CD3+ T cells and CD68+ macrophages and effectively promoted infected wound healing in diabetic rats. This work improves our understanding of the antibacterial mechanism of AgNPs-based nanocomposites and offers guidance to activity prediction and rational design of effective antimicrobial nanoparticles.

Abstract
Electrospun nanofibers showing great promise for fabricating nanostructured materials might help to improve the quality of wound care. The present study aimed to investigate the wound-healing potential of collagen nanofiber mats containing silver nanoparticles. Silver nanoparticles (AgNPs) synthesized by the chemical reduction method were incorporated in collagen nanofibers during the electrospinning process. Characterization of electrospun nanofiber mats revealed a mean fiber diameters in the range of 300-700 nm with a sustained release of silver ions shown to follow pseudo-order kinetics. MIC of AgNPs against Staphylococcus aureus and Pseudomonas aeruginosa were evaluated using micro-dilution assay and further antimicrobial activity of fabricated nanofibers was performed. Finally, in vivo studies were performed to demonstrate the wound-healing efficacy of composite nanofibers. In vitro results confirmed the potential antimicrobial efficacy provided by AgNPs and AgNPs composite nanofibers, essential to provide an aseptic environment at the wound site. In vivo study revealed that the rate of wound healing of the composite nanofiber mats was found to be accelerated compared with plain collagen nanofibers. Histology analysis revealed an accelerated re-epithelization, collagen production, and better wound contraction with AgNPs composite collagen nanofibers.
