Patent ID: 8183057

Claim:
A biomaterial structure comprising mutually-linked particulate lumps, each of which includes a principal chain of at least one biomaterial and at least one compound capable of binding to the biomaterial, wherein the particle diameter of the particulate lumps is 10 μm or smaller, wherein the weight ratio of the biomaterial to the biomaterial structure is 0.1 or higher, the principal chain is formed by binding the biomaterial to the compound for binding through a binding functional group and repeating the biomaterial and the compound binding to each other to form a chain and/or reticular structure, and the principal chain has two or more partial structures of Formula (A), R 1 -R 2 Formula (A) wherein R 1 is the biomaterial and R 2 is the compound for binding, and each of R 1 and R 2 may be the same or different.
