title: Development of hyaluronic acid-Fe2O3 hybrid magnetic nanoparticles for targeted delivery of peptides.
abstract: Novel hybrid nanoparticles comprised of hyaluronic acid (HA) and iron oxide were synthesized and characterized for the first time with the average diameter of less than 160 nm. The iron oxide (Fe2O3) particles are hybridized between HA layers by electrostatic interactions between the positive surface charge of the Fe2O3 nanoparticles and the negative charge of the carboxylate groups of HA, forming a corral-like structure. The particles were also characterized by FTIR and NMR to verify the hybridization. The particles were tested for their ability to deliver peptides to the cells using HEK293 and A549 cells. Results show that these particles delivered peptides at about 100% level. These HA-iron oxide nanoparticles are expected to be useful in developing effective tissue and cell targeting systems.
