Symposium TT: Interfaces in Materials, Biology, and Physiology

Interfaces in Materials, Biology, and Physiology

High-performance engineering materials can exhibit property amplifications similar to those observed in natural composites such as wood, sea shell nacre, and bone.  While the ability to relate such mechanical properties to hierarchical structure is gaining in maturity, careful control of the interfaces and interphases between constituents remains challenging.  Harnessing such knowledge will aid the design of advanced materials such as attaching composite wings to aircraft, as well as enable the development of solutions for tendon-bone reattachment, rotator cuff repair, and bone regeneration.

The aim of this symposium is to provide a forum for materials scientists, chemists, biologists, physicists, bioengineers, and clinicians to interact in a multidisciplinary environment to present their research on interfaces in natural and synthetic materials as well as on interfaces between biology and materials.  The symposium will integrate key topics in many areas of mechanics and materials dealing with micromechanics, continuum methods, numerical methods, and experiments that investigate mechanical response in biological and bioreplacement systems at the micro- and nano-length scale.  In addition, the role of mechanics at the cellular and tissue level and its medical implications will be discussed.  Interactions between experimental and computational aspects are especially significant in biological systems due to the complexity and hierarchy of structure due to the scientific and computational challenges encountered in modeling biological systems.  Here, central challenges exist at each hierarchical level, from understanding how attachment occurs at the macroscopic level to understanding how attachment drives molecular cues to cells at the nanoscopic level.

The potential impact of the integration of biology and materials science defines the scope of this bioderived and bio-inspired symposium.  There-fore, the focus of the symposium is both timely and important.  Applications of the presented research will form part of the core mission of many agencies and should be of interest to researchers in diverse fields as well as the NSF, NIH, DOE, and DOD, among others. 

Session topics will include:

  • Pericellular and extracellular environments, and their role in guiding cell biophysics, biochemistry, gene expression, and differentiation
  • Structural attachment of dissimilar materials in nature, physiology, engineering, and surgery
  • Thermal and mass transport across tissues and interfaces in nature and engineering
  • Photonics and optoelectronics in nature
  • Multifunctional hybrids in nature and engineering
