The Effect of Nanoconfined Liquid Properties on the Water-Responsive Behavior of Bacterial Cell Walls
<p>Water-responsive (WR) materials have the ability to mechanically swell and shrink in response to changes in relative humidity (RH). These WR materials are used by many biological systems to perform essential tasks; for example, pinecones use WR materials to release their seeds in dry …

Development of an Injectable Methylcellulose Hydrogel System for Nucleus Pulposus Repair and Regeneration
… the most common cause of disability in the world and is often caused by degeneration or injury of the intervertebral disc (IVD). The IVD is a complex, fibrocartilaginous tissue that allows for the wide range of spinal mobility. Disc degeneration is a progressive condition believed to begin in the …
