Plasticized agarose films: A physicochemical, mechanical and thermal study.

Agarose uniquely forms moldable biodegradable films, making it a promising renewable material with exceptional biocompatibility, thermo-reversibility, and flexibility. However, agarose films lose most of their flexibility at low moisture content. One way to assuage this issue is to incorporate plasticizing agents.

Ultrasound regulated flexible protein materials: Fabrication, structure and physical-biological properties.

Ultrasound can be used in the biomaterial field due to its high efficiency, easy operation, no chemical treatment, repeatability and high level of control. In this work, we demonstrated that ultrasound is able to quickly regulate protein structure at the solution assembly stage to obtain the designed properties of protein-based materials. Silk fibroin proteins dissolved in a formic acid-CaCl solution system were treated in an ultrasound with varying times and powers.
