Figure 2.
(A) Temperature versus irradiation time and (B) high-frequency MF of the PMNSs suspensions with concentrations of 5 mg/mL in distilled water. Irradiation and MF were done with 808 and 540 nm, and 4 and 8 kA/m, respectively. (C) PMNSs and Lf-PMNSs sizes distribution determined by DLS, (D) thermogravimetric analysis of PMNSs, Lf-PMNSs and Lf-Doxo-PMNSs, and the weight loss of them after 350 °C heating, (E) XRD patterns of as-synthesized PMNSs and Lf-PMNSs, (F) magnetization curves at room temperature for PMNSs, Lf-PMNSs and Lf-Doxo-PMNSs, (G) N2 adsorption–desorption isotherms, and (H) drug loading and its efficiency.
