Materials & Methods Synthesis Procedure of PDA@MT Polydopamine is synthesized through covalent polymerization similar to melanin biosynthesis‚ with DA oxidized to dopamine quinone‚ then further oxidized to DHI‚ which undergoes deprotonation and cross-linking via Michael addition to form PDA. A solution was prepared to synthesize PDA by mixing 90 mL of water‚ 40 mL of ethanol‚ and 3 mL of ammonia solution in a 300 mL beaker. After stirring for 30 minutes at 37°C‚ a solution of 500 mg of DA dissolved
