Radiation synthesis and characterization of micro and nano particles of acrylated palm olein for use in drug delivery

Emulsion polymerization and crosslinking reaction of acrylated palm olein (APO) in the presence of anionic and nonionic group surfactants were carried out by gamma irradiation. The critical micelle concentration (CMC) and formation of micro micelles as well their properties were determined their re...

Using thymoquinone as a model bioactive compound, a drug loaded APO micro and nanoparticles were synthesized. Size of the thymoquinone-loaded APO micro or nanoparticle was in the range of 140 to 300 nanometer after irradiation using gamma irradiator. The presence of the bioactive and surface active compounds in the micro and nanomicelles determined the particle size and stability, and the bioactive release rate. This radiation-induced method provides a free initiator induced and easy to control process as compared to that of the classical or chemical initiator process.
