“…Nanofibers as materials can be used as a platform in Raman spectroscopy [81], in immunoanalysis [82], for air filtration [83] and as a pseudo-enzyme [84]. As can be seen, the AgNPs, besides their important wound treatment activity, which is summarized in Table 3 below, can be used also for disinfection and catalytic purposes.…”

Silver nanoparticles (AgNPs) have recently become very attractive for the scientific community due to their broad spectrum of applications in the biomedical field. The main advantages of AgNPs include a simple method of synthesis, a simple way to change their morphology and high surface area to volume ratio. Much research has been carried out over the years to evaluate their possible effectivity against microbial organisms. The most important factors which influence the effectivity of AgNPs against microorganisms are the method of their preparation and the type of application. When incorporated into fabric wound dressings and other textiles, AgNPs have shown significant antibacterial activity against both Gram-positive and Gram-negative bacteria and inhibited biofilm formation. In this review, the different routes of synthesizing AgNPs with controlled size and geometry including chemical, green, irradiation and thermal synthesis, as well as the different types of application of AgNPs for wound dressings such as membrane immobilization, topical application, preparation of nanofibers and hydrogels, and the mechanism behind their antimicrobial activity, have been discussed elaborately.

“…Hydrogels have excellent capacity to absorb wound exudates and at the same time maintain the moisture in wound environment to ensure proper healing. Hydrogels form impermeable physical barrier on wound surface and prevent bacterial invasion (Figure 1) and apart from that hydrogels also showcased its tendency to absorb wide range of metals [59,96,107,108]. Some silver nanoparticles incorporated hydrogels showed excellent wound healing activity as shown in Table 4.…”

Microbial infection remains all time and unresolved challenge in the management of burns and diabetic wounds. Especially in diabetic wounds infections are prominent reason of amputations. Microbial biofilms pose tough polymeric barrier that is difficult to cross by conventional antibiotics. Therefore, traditional approach of infection control using antibiotics is now failing at some extent that raised a need to shift this paradigm. Presently, silver nanoparticles incorporated scaffolds representing a new concept of nanoparticle dressings which is becoming popular in wound management. Recently developed silver nanoparticles functionalized wound dressings exhibited excellent profile in the management of wound infections and promotion of wound healing. This chapter throw light on the recent strategies used in the development of silver nanoparticles functionalized wound dressings and their outcomes along with potential benefits and future challenges in wound management.

“…The nanotubular carbon material prepared by the template method possesses a uniform morphology, large specific surface area, and good electrochemical performance, which makes it favorable for SC devices . However, the nanotubular carbon templates, such as polystyrene fibers, polyacrylonitrile fibers, MnO 2 -nanorods, ZnO nanowires, and tellurium nanotubes, usually have to be presynthesized by a complicated process, and additional template removal steps are needed with hazardous/corrosive solvents. The harsh treatment conditions may damage the architecture of the products to some extent .…”

A nitrogen-doped nanotubular carbon (N-NTC) aerogel with high porosity was synthesized via a simple in situ template-growth approach using melamine-cyanuric acid (MCA) supramolecular aggregates as the template-forming agent and nitrogen source for high-performance supercapacitors (SCs). MCA/carbon (MCA/C) aerogel was first synthesized through in situ reassembly of MCA to form a rodlike template and polymerization of glucose at the periphery of the MCA template under hydrothermal conditions, and then, the N-NTC aerogel with high N-doping and high porosity was obtained by subsequent pyrolysis of MCA/C and decomposition of MCA. The as-prepared N-NTC aerogel presented a unique one-dimensional structure with a high N content, superhigh specific surface area, large internal diameter, and uniform wall thickness. The formation mechanism of the N-NTC aerogel was analyzed systematically, and the morphology, structure, and chemical properties of the resultant N-NTC aerogel were fully investigated at different carbonization temperatures. As the electrode material of SCs, the N-NTC aerogel obtained at 900 °C carbonization and delivered a superior specific capacitance of 563 F g −1 at 1 A g −1 . The corresponding symmetric SC device exhibited a high energy density of 21 Wh kg −1 at a power density of 1217 W kg −1 . This method is also applicable to the synthesis of many other carbohydrate-based N-NTC aerogels.
