The objective of the present work was to develop a new drug nanocarrier consisting of nanoparticles made of glycol chitosan (Gc) and eicosapentaenoic acid (EPA). A primary amine of Gc was modified with EPA to prepare a hydrophobically modified Gc (EPA-Gc). The modified chitosan formed self-aggregates in an aqueous phase by intermolecular association between hydrophobic EPA attached to glycol chitosan. We have found that EPA-Gc nanoparticles can deliver multiple poorly water-soluble drugs. EPA-Gc nanoparticles were characterized in terms of size, zeta- potential, stability and drug release. The result showed that these chitosan derivatives were able to self-assemble and form spherical shape polymeric nanoparticle with the size about 90–580nm and zeta potential range of 13.94-20.33mV, depending on concentration of EPA. The size of EPA-loaded EPA-Gc nanocarrier was reduced with increasing the loading efficiency of EPA, due to the enhanced hydrophobic interaction between hydrophobic drug and hydrophobic segment of EPA-Gc. This study presents a new way to nano carrier long chain polyunsaturated fatty acids like EPA, useful for enrichment of hydrophobic drugs for delivery and release properties.
