We have recently developed a slide-ring gel that is different from physical and chemical gels by crosslinking polyrotaxane, a necklace-like supramolecule. Slide-ring gel, consisting of movable ...

While it is easy to thread a bead on a string in the macroscopic world, this is not always the case on molecular, nano- and microscopic length scales. We are developing new nano- and microscale ...

Hydrogels have promise as tissue engineering scaffolds and in other biomedical applications. But these materials, which are made mostly of water held together by hydrophilic, cross-linked polymers, ...
