Magnetic nanoparticles, in particular iron oxide (also called magnetite or Fe3O4)ĭepartment of ClinicalMedicine, Institute of Molecular Medicine, Trinity College Dublin, Dublin, IrelandĢCentre for Research on Adaptive Nanostructures and Nanodevices, Trinity College Dublin, Dublin, Irelandįulllist of author information is available at the end of the article The development of nanoparticles as controlled drug delivery and disease detection systems has emerged as one of the most promising biomedical and bioengineering applications of nanotechnology. Keywords: Nanomedicine, Magnetite nanoparticles, Quercetin, Drug delivery, Nebulization This study has implications for targeted delivery of therapeutics and poorly soluble medicinal compounds via inhalation route.

The drug-loaded PLGA-MNPs significantly reduced the number of viable A549 cells, which was comparable when applied either by nebulization or by direct pipetting.Ĭonclusion: We have developed a magnetic core-shell nanoparticle-based nanocarrier system and evaluated the feasibility of its drug delivery capability via aerosol administration. To imitate aerosol formation for drug delivery to the lungs, we applied quercitin loaded PLGA-MNPs to the human lung carcinoma cell line A549 following a single round of nebulization. Moreover, the PLGA-MNP preparation was well-tolerated in vivo in mice when applied intranasally as measured by glutathione and IL-6 secretion assays after 1,4, or 7 days post-treatment.

Utilizing a series of standardized biological tests incorporating a cell-based automated image acquisition and analysis procedure in combination with real-time impedance sensing, we confirmed that the developed MNP-based nanocarrier system was biocompatible, as no cytotoxicity was observed when up to 100 |g/ml PLGA-MNP was applied to the cultured human lung epithelial cells. Results: Average particle size of the developed MNPs and PLGA-MNPs as measured by electron microscopy was 9.6 and 53.2 nm, whereas their hydrodynamic swelling as determined using dynamic light scattering was 54.3 nm and 293.4 nm respectively. The polymeric shell of these engineered nanoparticles was loaded with a potential anti-cancer drug quercetin and their suitability for targeting lung cancer cells via nebulization was evaluated.

To address this need, we synthesized and characterized a biocompatible drug delivery vehicle following surface coating of Fe3O4 magnetic nanoparticles (MNPs) with a polymer poly(lactic-co-glycolic acid) (PLGA). In this context, there is an urgent need to develop novel nanocarriers suitable for drug delivery by nebulization.
