In order to heal the larger wound, the skin surface must be covered with sufficient Tenofovir concentration dressing, even it is temporary. An ideal wound dressing should do the following: (1) Maintain a moist environment around the wound. (2) Permit diffusion of gases. (3) Remove excess exudates but prevent saturation
of the dressing to its outer surface. (4) Protect wound from microbes and not contaminate the wound with foreign particles. (5) Provide mechanical protection. (6) Control local temperature and pH. (7) Be easy and comfortable to remove and change. (8) Minimize pain from the wound. (9) Be nontoxic. (10) Be cost-effective and cosmetically acceptable. (11) Prevent wound desiccation. (12) Stimulate the growth factors and be biocompatible and elastic. (13) Reduce malodor. (14) Conform to the site and shape of the wound. (15) Assist in wound bed preparation, such as debridement. (16) Satisfy patient and clinician expectations.66 and 67 Dressings made with learn more biometrics are becoming popular because of their many advantages. Impaired wound healing because of infections and other above-mentioned complications spurred the search for drug-loaded dressings.68 Drug-loaded dressings are prepared by incorporating drugs
such as antibacterials and antibiotics in the dressings. When applied to a wound, drug-loaded dressings act as a barrier to microorganisms and thus prevent secondary infections, while stimulating the wound-healing environment. Therefore, drug-loaded dressings are useful in preventing secondary infections on the wound and promoting fast wound healing. However, the ability of cotton fibers to absorb large amounts of moisture makes them more prone to Montelukast Sodium microbial attack under certain conditions of humidity and temperature.37 Moreover, cotton are serves as a medium for the growth of bacteria and fungus.69 For this reason, cotton fibers are treated with numerous chemicals to get better antimicrobial cotton textiles. Among the various antimicrobial agents, silver nanoparticles have shown strong inhibitory
and antimicrobial activity and have no negative effect on the human body.70 These particles can be incorporated into several kinds of materials, such as clothes. Clothes incorporating with silver nanoparticles are sterile and can be used to prevent or to minimize infection with pathogenic bacteria. Nowadays, metal-based topical dressings have been widely used as a treatment for infections in burns, open wounds, and chronic ulcers.71 Silver nanoparticles were incorporated by physical means; before being used, cotton fabrics were washed, sterilized, and dried, then submerged in an Erlenmeyer flask containing silver nanoparticles and agitated at 600 rpm for 24 hours and dried at 70°C, then cured at 150°C. The schematic representation of the formation of metal nanoparticles on cotton fabrics is presented in Figure 4. Rujitanaroj et al.
