Structural properties of control tetrakis(Carboxyphenyl) porphyrin (C-TCPP)- and redox-responsive tetrakis(carboxyphenyl) porphyrin (RR-TCPP)-polysilsesquioxane nanoparticles (PSilQNPs).
| Sample | Diameter (nm) * n = 3 | PDI | ζ-Potential (mV) * n = 3 | Aromatic Content (%) | Loading of TCPP (µmol/g) |
|---|---|---|---|---|---|
| C-TCPP-PSilQNPs | 183.8 ± 10.5 | 0.39 | −39.7 ± 2.8 | 10.1 | 127.7 |
| RR-TCPP-PSilQNPs | 144.3 ± 15.0 | 0.33 | −44.5 ± 2.5 | 11.3 | 142.0 |
* Data measured in phosphate buffer solution (1 mM; pH 7.4)/Concentration of PSilQNPs = 0.1 mg/mL; PDI = Polydispersity index.
