It is clear that the lowest coefficient of variation and, therefore, lowest polydispersity were found for the SIPPs synthesized with the TDA and DDA, in agreement with the qualitative analysis of the TEM images. It should be noted, though, that the DDA used to synthesize the DDA-SIPPs was corrosive and corroded part of the inside of the septum used with the reflux apparatus. For this reason, the SIPPs synthesized with TDA (TDA-SIPPs) appear to be a better option, striking an appropriate balance between ZD1839 solubility dmso the safety aspects of synthesis and delivering the lowest polydispersity of the final nanoparticles synthesized. learn more Table 1 Structural characterization of SIPPs Value Description Units 18SIPP30 18SIPP60 16SIPP30 16SIPP60 14SIPP30 14SIPP60 12SIPP30 12SIPP60 L Chain length – 18 18 16 16 14 14 12 12 t Reflux time min 30 60 30 60 30 60 30 60 d Diameter nm 11.29 ± 3.22 7.20 ± 1.81 6.83 ± 1.34 5.14 ± 2.13 7.34 ± 1.22 6.14 ± 1.67 7.92 ± 1.29 7.34 ± 1.12 CV Coefficient of variation % 28.49 25.1 19.6 41.5 16.6 27.3 16.3 15.3 V p Particle volume cm3 1.95 × 10−18 1.96 × 10−19 1.67 × 10−19 7.12 × 10−20 2.07 × 10−19 1.21 × 10−19 2.60 × 10−19 2.07 × 10−19 S Surface area cm2 7.55 × 10−12 1.63 × 10−12 1.47 × 10−12 8.31 × 10−13 1.69 × 10−12 1.19 × 10−12 1.97 × 10−12 1.69 × 10−12 C p Suspension concentration mg/mL 9.33 ± 0.70 18.30 ± 0.00 5.36 ± 0.43 4.92 ± 0.13 4.29 ± 0.47 5.68 ± 0.43 3.22 ± 0.25 4.74 ± 0.40 C Fe Iron concentration mg/mL
