Polydopamine coating has been issued in the past decade due to its unique material-independent surface modification ability, and there have been many demonstrations of co-deposition of amine-, thiol-containing molecules with dopamine to form Michael addition. However, co-deposition with aldehyde group has been rarely attempted. In this work, dopamine and aldehyde were co-polymerized through Schiff-base reaction, and the rapid reaction allowed formation of aggregates that can be deposited on various substrates. Modified substrates was successfully functionalized by aldehyde coupling demonstrating anti-fouling and controlling wettability. Interestingly, the resultant particles showed high a fluorescence signal, which remained even when the particles were coated on substrates. This novel fluorescent polydopamine particle shows great potential in bio-imaging applications such as live cell imaging. |
