研究领域

Silks are natural polymers with outstanding properties. Some spider silks are tougher than the toughest synthetic polymers and even outperform steel in terms of strength by weight. Also, because it is a biocompatible protein, silk is ideally suited for use in biomedical applications. The outstanding properties of silk are due to its interesting structure, featuring a peculiar organization down to molecular scales. We apply our imaging techniques to silkworm silk protein to provide unprecedented insights into assembly at single-molecule resolutions. This knowledge will help develop new processes to make silks artificially: novel materials that are environmentally completely benign and feature excellent mechanical properties. Our lab also studies the brown recluse spider, which spins a thin ribbon of silk instead of a cylindrical strand typical of other species. By applying our imaging and other characterization techniques to this ribbon morphology, we hope to reveal novel structural, adhesive, and mechanical insights that will help us manufacture artificial thin silk films with the impressive properties of a native brown recluse strand.
