    Abstract: The present invention provides a joined body with no risk of detachment from the joining surface without using an adhesive, and a method for producing the joined body. The present invention also provides a reversible joined body that enables control of joining and dissociation, and a method for producing the reversible joined body. In the joined body, a chemical bond is formed between two or more same or different solid-state materials at their contact interfaces by a chemical reaction.

    Abstract: Provided is a self-restoring macromolecular material that not only has excellent stress relaxation but that can also be easily restored to its original state, even when damaged or severed. Also provided is a method for producing the self-restoring macromolecular material. The self-restoring macromolecular material contains a crosslinked structure that is formed by crosslinking a polymer containing at least a polyrotaxane molecule. The polyrotaxane molecule is formed so as to include a cyclic molecule 21 and a linear molecule that passes through an opening 21a of the cyclic molecule. The crosslinked structure 1 is crosslinked via a reversible bond between the cyclic molecule of the polyrotaxane molecule and a polymer molecule other than the polyrotaxane molecule.

    Abstract: This invention provides a method for producing a polyrotaxane, the method being capable of producing a polyrotaxane in a high yield within a short period of time, using a small number of steps. The method for producing the polyrotaxane of the present invention is a method for producing a polyrotaxane having a structure in which a linear molecule passes through openings of cyclic molecules, the method comprising the step of heating a starting material containing the linear molecule and the cyclic molecule to the melting temperature of the linear molecule or higher, to obtain a clathrate compound of the linear molecule and the cyclic molecule.

    Abstract: Provided are: a polymer gel for a medium, and a medium in which the stiffness of the polymer gel can be easily and reversibly changed and the shape of cells can be controlled according to the stiffness of the gel; and a method for culturing cells using the medium. The polymer gel for a medium contains a solvent and a crosslinked structure that is crosslinked by reversible bonds. The stiffness of the polymer gel for a medium can be easily and reversibly changed. Accordingly, when the polymer gel for a medium according to the present invention is used, cell morphology and function can be reversibly controlled according to the stiffness of the gel.
