Catecholic moieties have attracted attention due to their participation in strong adhesion found in nature. In addition, their polymerization processes, i.e., biopigmentation processes such as melanogenesis and cuticle sclerotization, have inspired us to develop unique organic materials. Herein, we report a simple fabrication strategy of multifunctional catecholic pigments through the conventional ink-jet printing. We observed that ink-jet printed horseradish peroxidase (HRP) guided site-specific polymerization of catecholic precursors, which was further attached/localized near HRP due to the given adhesive properties. Fabricated polycatecholic pigment showed good biocompatibility and photothermal conversion ability by NIR adsorption like natural melanin. We expect this fabrication method can provide a versatile platform for multifunctional organic patterns utilizing in biomedical applications. |
