Research Areas

Our team aims to create water-based materials, referred to as "aqua materials", as replacements for conventional plastics. Taking advantage of their unique properties as "moldable, portable water", together with the elaboration of their inner or surface part, we will demonstrate their various applications as intelligent soft materials. We are employing a wide range of chemicals as the components of aqua materials, in order to improve their properties and to realize ultimately environment conscious materials. The challenge of our team also includes the rational design of novel bioinspired materials, by assembling molecules with dynamic and static functions within aqua materials as scaffolds.

Research Subject

  1. Chiral solid-state hosts based on the molecular imprinting in liquid crystals
  2. Chiral molecular flasks based on the template reactions in liquid crystal
  3. Aqua materials; ultimate environment-conscious alternatives to conventional plastic based on hydro-gels
