Welcome to the Hsiao Lab at NCSU!
The movement and transport of fluids is an integral part of Life – our joints move because of lubrication forces, cells migrate and take up nutrients in hydrated environments, our viscoelastic mucus system flushes out invading bacteria. How can we get creative with these processes given an understanding of their microscopic origin?
Our group’s research interests are in the areas of soft biomaterials and complex fluids – specifically on the use micron-sized colloids with interesting shapes and geometries. We work on a fundamental level with these particles to engineer the mechanical properties of soft surfaces. Our work can be applied to the biomechanics of lubricated joints that make movement possible in humans and animals, and in the development of new types of materials with directional properties that are not found in nature. We use an interdisciplinary approach that combines experiments and models from materials science, chemical engineering, physics, and bioengineering to understand the roles of structure and dynamics in these systems. Our group uses anisotropic particles, multi-dimensional lithographic printing, and a combination of high-speed microscopy and flow characterization techniques to achieve optimal mechanical and functional properties in a broad class of bio-inspired materials.
