Jiyu Fang’s research focuses on the interdisciplinary area of physics, chemistry, materials and biology, with an emphasis on self-organized biological systems and self-assembled nanostructural materials. Technology development such as scanning probe microscopy, liquid crystal optical amplification and soft lithography also plays a major role in his research activities. This area has rich opportunities for students both in fundamental science and practical technologies. There are four current projects in Fang’s group:

  • Imaging order, defects, and dynamics of biological interfaces with liquid crystals
  • Stretching polymers and biopolymers in thin films with a scanning probe microscope
  • Nanomaterials based on self-assembly of biological building blocks such as lipids, peptides, DNA and Virus
  • Protein crystal-directed assembly of 2-D and 3-D inorganic nanocrystals
Research interests:

  • Biological interfaces
  • Nano-scale science and engineering
  • Molecular self-assembly
  • Polymer thin films
  • Biotechnology
  • Soft lithography
  • Scanning probe microscopy
  • Liquid crystal imaging techniques
