Abstract
Provided is a bio-hybrid material that does not cause elution of nickel ions and has an excellent endothelialization ability, a production method therefor, and a stent. The bio-hybrid material (101) used includes an alloy part (11) free of Ni, an organic acid (12) having two or more active esters, and a cytokine (13). The alloy part (11) free of Ni forms an ester bond with the organic acid (12), and the organic acid (12) and the cytokine (13) are immobilized via an amide bond.
