Wound dressings primarily contribute to the wound healing process by protecting the wound from microorganisms and infection. Ideal wound dressing materials are flexible, biodegradable, allow gas transmission, and possess protective properties. In addition, they must control the absorption of exudate from the injured area. While traditional dressings are effective in the initial phase of healing by preventing bleeding and shielding the wound from the environment, their sole use can cause them to

Soap foams because soap molecules reduce the surface tension of water; this allows bubbles (small air pockets) to form between water and air.The Two Ends of the Molecule – What Is Soap?One end of a soap molecule loves water (hydrophilic, from “hydro‑=water” and “‑philic=loves”), while the other end repels water (hydrophobic), meaning “water-avoiding”.When water and air meet, this unique structure helps the water spread out like a thin film and traps air, creating foam.Reduction of Surface Tensio
