Figure 4. Characterization of Cur@NCPs.

Figure 4.

(A) UV-vis spectra of curcumin in acetone (orange) and NCP nanoparticles in deionized water before (red) and after (blue) entrapping curcumin. (B) TEM image of Cur@NCPs. (C) Size distribution of Cur@NCPs. (D) Encapsulation efficiency and loading capacity of Cur@NCPs using different volumetric ratios of CHCl3 to deionized water. Control1 and Control2 indicate encapsulation efficiency and loading capacity of a 1 mL PMPC-b-PserA solution (10mg/mL) without Fe3+ with addition of 200 µL curcumin in CHCl3 (4 mg/mL).
