Spray-on skin. Artificial skin being sprayed onto an arm as an electrosol (electro-aerosol). If put onto a cut or burn, the fibres may prevent scarr- ing. The artificial skin is made from a solution containing long chemical chains (polymers). The solution is charged so it is attracted to the skin as a spray. The 5-micrometre-diameter biodegrad- able fibres form a mesh that provides a temporary scaffold for fibroblasts to grow on. These cells form collagen, the protein that makes skin strong and supple. Normally, wounds heal quickly to prevent infection, sometimes leading to scarring. However, the polymer mesh may allow normal skin to form. Photographed at Electrosols, UK.
