In biological systems, life process is led by the unique behavior of macromolecules such as proteins and DNA. Molecular recognition by macromolecules plays an important role, for example, in substrate specificity of enzymes and antigen-antibody reactions in human life. Selective molecular recognition among macromolecules is achieved through a large number of weak interactions. We have focused our attention on the special behavior of antibodies, especially monoclonal antibodies, because they can recognize a larger and more complicated compound with high specificity than that can synthetic host molecules or enzymes.
In this laboratory, we develop novel materials through hybridization of bio-related macromolecules such as monoclonal antibodies with artificial/synthetic small molecules. We construct functionalized catalytic and energy conversion systems based on specific molecular recognition of biomacromolecules and selective assembly of bio/synthetic molecules.
