pH-Responsive Self-Assembly by Molecular Recognition on a Macroscopic Scale

Macroscopic pH-responsive self-assembly is successfully constructed by polyacrylamide-based gels carrying dansyl (Dns) and β-cyclodextrin ( βCD) residues, which are represented as Dns-gel and βCD-gel, respectively. Dns-gel and β CD-gel assemble together at pH 4.0, but disassemble at pH 3.0. The adhesion strengths for pairs of Dnsgel/βCD-gel increase with increasing pH.
