Outline of Final Research Achievements

In biological systems, there are various types of functional molecules and their assemblies which are sequentially-controlled, as represented by genetic code or DNA transcription systems. Such regulated assemblies play important roles to form macroscopic organizations based on selective molecular recognition. In artificial systems, macroscopic self-assemblies have been achieved mainly through macroscopic physical interactions. We developed various stimuli-responsive macroscopic assemblies based on polymeric hydrogels modified with cyclodextrins (CDs) and guest molecules. The gel assembly and dissociation can be controlled by various external stimuli. Such macroscopic assemblies remind us of the selective formation of cell organization.
