Schematic illustration of PFOB nanocapsule is shown in Figure 1.
Influence of PLGA-PEG Percentage to PFOB Nanocapsule Characteristics.
NC40% demonstrated stronger phagocytosis hindrance than PFOB nanocapsules with lower PLGA-PEG percentages, while higher PLGA-PEG percentages did not significantly increase this capability.
PFOB nanocapsule size (dH) decreased from approximately 150 nm to less than 100 nm when total polymer mass was reduced from 100 mg to 40 and 20 mg, as measured by the DLS method (Table 1; middle row).
The average particle size of optimal PFOB nanocore template was 131.5 [+ or -] 4.3 nm.
Since it is time-saving and convenient and allows control of the particle diameter, it was used in this research to prepare PFOB nanocore template.
Therefore, ultrasonic preparation determined in our study is more suitable for optimal PFOB nanocore template.
To avoid the aggregation, PFOB nanocore template dispersion solution was dropped into FA-PEG-CS-FITC acetic acid aqueous solution with gentle magnetic stirring.
Compared with PFOI, both PFOB and PFOC showed no estrogenic activity.
PFOB concentration of supernatant liquor was measured by gas chromatograph (GC) at 300[degrees]C, using flame ionization detector (FID).
Encapsulation efficiency of the nanoparticles was 80.43 [+ or -] 0.96%, and the concentration of PFOB in NPs solution was 10.09 mg/ml.
The results showed that, with the same PFOB concentration of NPs and MPs (10 mg/ml), the ultrasonic signals of NPs were weaker, but there was no statistical difference between the two groups (Figure 4(b)).
