Iron oxide nanoparticles (ION) have been used recently as a drug delivery system and as a contrast agent for MRI diagnosis. The ION's can work as vectors with specific surface modifications to amplify the bioactive compound effect, enhance the liberation of specific drugs or interact with certain surface as cell membranes and biomolecules [1]. This works aims to the development of ION's with surface modifications to increase the interactions with plasmid DNA (pVAX1-NH36). The objective is to synthesize ION's stabilized with hydrophobic compounds and modified with a natural flavonoid (baicalin) [2, 3], recognize as selective attractive molecule for the DNA. Probable applications are in its use for DNA mechanical purification and as an intracellular contrast agent for DNA.
