New doxorubicin nanoparticles engineered from calcium-crosslinked carbomer and a microemulsion precursor Academic Article uri icon

abstract

  • The purpose of this study was to investigate a new polymeric system and production process in which self-assembled doxorubicin-loaded nanoparticles were synthetized by using a water-in-oil microemulsion as a template and calcium ions as cross-linkers. The manufacturing process combined cross-linking of carbomer within a W/O microemulsion followed by a phase-separation technique to avoid using organic solvents for extraction. To assess the sustained release behavior of doxorubicin from the nanoparticles, we have developed a new simple method based on the permeability coefficient of a synthetic membrane mounted on Franz diffusion cell system. Franz cells were preferred over the commonly used dialysis tubing because they provide adequate measures of the diffusion area as well as the volumes of the media in both sides of the membrane. The lower …
