“…Kharaghani et al [ 52 ] did the design and combining polyacrylonitrile/silver (PAN/AgNPs) nanofibers by using an in-situ method. The goal was to achieve a washable with high-dispersed silver nanoparticles membrane to produce the hierarchically organized antibacterial mask to avoid the two-way effect of bacteria from person to environment and environment to person.…”

The masks have always been mentioned as an effective tool against environmental threats. They are considered as protective equipment to preserve the respiratory system against the non-desirable air droplets and aerosols such as the viral or pollution particles. The aerosols can be pollution existence in the air, or the infectious airborne viruses initiated from the sneezing, coughing of the infected people. The filtration efficiency of the different masks against these aerosols are not the same, as the particles have different sizes, shapes, and properties. Therefore, the challenge is to fabricate the filtration masks with higher efficiency to decrease the penetration percentage at the nastiest conditions. To achieve this concept, knowledge about the mechanisms of the penetration of the aerosols through the masks at different effective environmental conditions is necessary. In this paper, the literature about the different kinds of face masks and respiratory masks, common cases of their application, and the advantages and disadvantages of them in this regard have been reviewed. Moreover, the related mechanisms of the penetration of the aerosols through the masks are discussed. The environmental conditions affecting the penetration as well as the quality of the fabrication are studied. Finally, special attention was given to the numerical simulation related to the different existing mechanisms.

“…The antibacterial activity of metallic (silver, gold, copper, platinum) nanoparticles and metallic oxide (ZnO, TiO 2 , Ag 2 O, Fe 2 O 3 , CuO, CaO, MgO and SiO 2 ) nanoparticles have been investigated for the in‐vitro and in‐vivo but Ag nanoparticles showed the appreciable results for antibacterial activity and also biocompatibility, therefore it could use preferably in various medical applications such as antibacterial, antiviral, antifungal and also inflammatory agents but silver sulfadiazine (SSD) is the more attractive agent for diverse biomedical applications. More especially, SSD has been demonstrated to act as strong adsorbents to disturb the biochemical route of microbial by formation of reactive oxygen and electron transfer reactions.…”

The surface modification of nanofibers web enables the invention of wound dressings by using the simple materials substrate without altering the mechanical properties of foundation materials or nanofibers web. Herein, authors fabricated the novel antibacterial wound dressings by functionalizing the surface of cellulose acetate (CA) nanofibers. This surface treatment was done through facile method. The silver sulfadiazine (SSD) nanoparticles were successfully synthesized on the surface of cellulose acetate nanofibers web by in-situ facile method in which nanofibers webs were immersed in the solution of sodium sulfadiazine salt and silver nitrate (AgNO 3 ) for three different interval of times (hrs). The resultant CA/SSD nanofibers were characterized by scan electron microscope, transmission electron microscope, FT-IR, XPS, XRD, water contact angle and antibacterial agar disc diffusion test. All characterization results supported that this composite can be used for antibacterial wound dressings, especially for gram negative E. Coli bacteria because SSD has great potential against E. Coli bacteria.[a] Dr.

“…Retina senses light and converts it into the neural signals and transfers neural signals to the brain and cause visual perception [2,3]. Nanostructures have evolved as multidisciplinary applications by combination with materials as an advanced architecture to develop functional substitutes for various proposes such as wound dressing [4][5][6], tissue engineering [7][8][9][10][11], and biomedical applications [12][13][14]. Neuroscience, related to the retina is one of the most exciting fields where nanostructures with modified properties serve as scaffolds to promote and facilitate the migration and adhesion of the cells [15].…”

Nanowires aim at developing advanced architectures are gaining popularity for damaged neural systems. The retina with a complicated structure is an essential part of our visual nervous system. Any disorder inside retina could lead to blindness due to irregularity in transferring neural signals to the brain. In recent years, the emergence of nanostructures, as well as nanowires, has provided a viable means for enhancing the regeneration of retinal. Nanowires with the ability to sense light and converting it to the electrical signals simulate the extracellular electrical properties, which are the newest nanostructures for the retinal applications. The different structure of nanowires has been examined in vitro, and several others are undergoing in vivo for vision recovery. Among the structures, core-shell nanowires and functionalized nanowires with gold nanoparticles attract the attention for the regeneration of retinal neural systems. Herein, subsequently provide an introduction to the anatomy of the retina, and retinal disorders, the latest progress in the regeneration of retina and vision using nanowires will be reviewed. Also, the different structures, including core-shell and functionalized nanowires with nanoparticles, will be examined. Eventually, the point of view and perspective of applying nanowire in retinal regeneration will be offered.
