ANTIMICROBIAL ADHESIVE PROTEIN, ANTIMICROBIAL NANOPARTICLE, ANTIMICROBIAL COMPOSITION COMPRISING SAME NANOPARTICLE, AND PREPARATION METHOD FOR SAME COMPOSITION

Abstract:

The present invention relates to an antimicrobial adhesive protein, an antimicrobial nanoparticle, an antimicrobial composition comprising the same nanoparticle, and a preparation method for the same composition and, more particularly, to an antimicrobial adhesive protein in which an antibiotic peptide is linked to a mussel adhesive protein, a mussel adhesive protein derivative in which a tyrosine residue within the antimicrobial adhesive protein is modified with a catechol derivative, an antimicrobial nanoparticle including a metal capable of forming a coordinate bond with a derivative of the mussel adhesive protein and having intrinsic antimicrobial activity, an antimicrobial composition comprising the same nanoparticle, and a preparation method for the same composition.
