bioadhesives. While the role of L-3,4-dihydroxyphenyl alanine (DOPA) for water-resistant strong adhesion has been extensively studied, aggregate formation and physical adsorption behavior of MAPs have not been well examined yet. Here, we investigated the degree of aggregation and attachment property using recombinant MAP having no DOPA residues. Chemical cross-linking of oxidized DOPA residues was not required for formation of aggregates, and increased kosmotropic property for anions and chaotropic property for cations allowed formation of aggregates for strong adsorption on hydrophilic surfaces. This study suggests that the initial step of MAP adhesion might be aggregation based on the physical property itself. Physical adsorption can be adjusted by salt ions in water solution for efficient attachment, followed by DOPA-mediated water-resistant strong adhesion.
