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.

First claim

The invention claimed is:

1. A joined body, wherein two or more same or different solid-state materials are joined directly by a chemical bond at their contact interfaces,
wherein the solid-state materials are:
a solid-state material containing a boronic acid group and a solid-state material containing an aryl halide group;
a solid-state material containing an azide group and a solid-state material containing an ethynyl group; or
a solid-state material containing a carboxy group and a solid-state material containing an amino group.

2. A joined body, wherein two or more same or different solid-state materials are joined directly by a chemical bond at their contact interfaces,
wherein the chemical bond is a coordinate bond,
wherein a gel containing an apoenzyme and a gel containing a cofactor are used as the solid-state materials.

3. A joined body, wherein two or more same or different solid-state materials are joined directly by a chemical bond at their contact interfaces, wherein the chemical bond is a hydrogen bond, and
wherein a gel containing a first nucleic acid base and a gel containing a second nucleic acid base complementary to the first nucleic acid base are used as the solid-state materials.

4. A joined body, wherein two or more same or different solid-state materials are joined directly by a chemical bond at their contact interfaces, wherein the chemical bond is a hydrogen bond, and
wherein the solid-state materials are gels containing an oligonucleotide.

5. A method for producing a joined body by reacting a solid-state material containing a boronic acid group and a solid-state material containing an aryl halide group at their contact interfaces in the presence of a catalyst.

6. A method for producing a joined body by reacting a solid-state material containing an azide group and a solid-state material containing an ethynyl group at their contact interfaces in the presence of a catalyst.

7. A method for producing a joined body by reacting a solid-state material containing a carboxy group and a solid-state material containing an amino group at their contact interfaces in the presence of a catalyst, wherein the solid-state material is at least one kind selected from gels, glass, wooden plates, plastic, metal plates, and paper.
