The spatiotemporal temperature distributions of NIR irradiated polypyrrole nanoparticles (PPN) were evaluated by varying PPN concentrations and the pH of suspensions. The PPN were synthesized by oxidative chemical polymerization, resulting in a hydrodynamic diameter of 98 ± 2 nm, which is maintained in the pH range of 4.2-10; while the zeta potential is significantly affected, decreasing from 20 ± 2 mV to -5 ± 1 mV at the same pH range.

- This study investigates how different formulation parameters impact the creation of poly-dl-lactic-glycolic nanoparticles using emulsification-solvent evaporation and nanoprecipitation techniques.
- The research focuses on varying factors such as polymer and tensoactive concentrations, organic solvent fractions, and sonication or injection speeds to influence the nanoparticles' characteristics.
- Through methods like dynamic light scattering and scanning electron microscopy, the study demonstrates that adjusting these parameters can lead to nanoparticles of specific sizes and stability, enabling consistent results in their preparation.
