Biomimetics : “Designing biomedical materials by mimicking marine materials”
 
  Marine microenvironment has much common with human body. Both systems are naturally saline, experience variation of control over fluid flow, fouling by flowing via macromolecules, and degradation of organics via cellular-level activities. These are just a few examples of matching biological and mechanical events both present in the human body and the marine environment. Understanding physics and chemistry of marine biomaterials will provide the scientists useful insights for designing biomaterials for biomedical application. Isolation and characterization of the load bearing precusors in marine biomaterials is a prerequisite for mimicking those materials. Therefore, we aim to isolate, to produce, and to characterize of novel load bearing biomaterials from marine organisms and material properties of these biomaterials will be further investigated by collaborative research with materials and physics departments  
   
     
 
Manufacturing biomimetic environmentally friendly materials
 
  Biomimetic approaches will help inspire new generations of building blocks and subsequent production of engineered materials. We seek to produce new intriguing building blocks for material fabrication by biotechnological methods. The building blocks can be assembled and tailored for fabricating materials of multifunctionality in many applications. X-ray diffraction and imaging studies at the synchrotron facility in Pohang accelerator laboratory (PAL) may reveal intriguing insights about the assembly of the engineered materials.  
   
     
 
Characterizing the properties and performance of biomimetic material
 
  Here, we seek to understand the properties and performance of biomimetic environmentally friendly materials. Mechanical and biomedical properties can be investigated with various mechanical and biotechnological techniques. The interfaces of the materials can be studied with Electron microscopes (SEM, TEM), X-rays (Synchrotron, XRD), Atomic Force Microscope (AFM) and Surface Force Apparatus (SFA). Especially, intermolecular interaction between the interfaces is one of the most important forces for material assembly. An apparatus most often used for direct measurements of the forces of interaction between two interfaces is the surface force apparatus (SFA). The SFA is an instrument that measures the magnitude and distance of the intermolecular forces between two surfaces by approaching, retracting or shearing from one another.
