  • Spider silk: Material of the future?
    Spider silk: Material of the future?

    Strong, tough, sticky, elastic and biodegradable, silk may be used for a mesh to support injured tissues, or as a temporary container for drugs, stem cells and growth factors. As scientists divine the secret of how spiders and silkworms make silk, they are finding ways to engineer silk into medical devices.
