Elastic gel to heal wounds A team of bioengineers has developed a new protein-based gel that, when exposed to light, mimics many of the properties of elastic tissue, such as skin and blood vessels. They now report on the new material's key properties, many of which can be finely tuned, and on the results of using the material in preclinical models of wound healing.
