Theses and Dissertations

Renewable and biocompatible silk protein materials with desired physical properties show promising applications in biomedical field. In this work, a set of protein-based composites with desired thermal and magnetic properties, enhanced by the appropriate distribution of nanofillers in the protein matrix in both 2D-film and 1D-fiber forms was investigated. Results indicate that secondary structures of silk protein materials regenerated by a formic acid-calcium chloride method are different from those of their respective natural silk fibers. Intramolecular beta-sheet structures were found to dominate these silk films, causing these regenerated samples to be water-insoluble but more flexible than traditional silk films with …
