Embodiment 1
[0071] (1) Fe 3 o 4 Preparation of @Dopa-PS Magnetic Nanoparticles
[0072] 1) Preparation of Dopa-CTA
[0073] S-1-dodecyl-S'-(α,α'-dimethyl-α"-acetic acid) trithiocarbonate (CTA, 0.3646g, 1.0mmol) and dicyclohexylcarbodiimide ( DCC, 0.3095g, 1.5mmol) was dissolved in 5mL of dry dichloromethane, under the protection of nitrogen, the dichloromethane suspension containing N-hydroxysuccinimide (NHS, 0.1726g, 1.5mmol) was added under ice-cooling, Stir overnight at room temperature. After the solvent is removed, the yellow crude product is obtained, and the equivalent product Suc-CTA is obtained after column chromatography. Under nitrogen and light-shielding conditions, Suc-CTA (1.14g, 2.47mmol) and dopamine hydrochloride (0.562 g, 2.96mmol) was added to 20mL of anhydrous methanol, and stirred at room temperature for 24 hours. The yellow crude product was obtained after the solvent was evaporated, and the yellow Dopa-CTA was obtained after purification by column chromatography,...
