| 제목 | Multifunctional polycatecholamine fabrication by conventional ink-jet printing |
| 초록 | Polydopamine is a representative melanin-like polycatecholic organics that has been widely used in surface engineering. It has been applied to a variety of substrates as a multifunctional coating as well as an adhesive layer for secondary functionalization. However, it often requires labor-intensive surface patterning process due to the difficulties in selective binding. Herein, we found that enzyme by ink-jet printer initiated polymerization of catecholic precursors, and simultaneous attachment of polycatecholic pigment was observed near the enzyme due to its adhesive properties. We expect convenient fabrication of multifunctional melanin-like materials can be applied to surface biofunctionaliation of medical devices. ** This work was supported by National Research Foundation of Korea (NRF) grants funded by the Government of Korea (MSIT): Basic Research Program in Science and Engineering (NRF-2020R1C1C1010700) and Engineering Research Center (ERC) program (NRF- 2018R1A5A1025511). |
