| Summary: | Krupa Kansara, Pal Patel, Ritesh K Shukla, Alok Pandya, Rishi Shanker, Ashutosh Kumar, Alok Dhawan Institute of Life Sciences, School of Science and Technology, Ahmedabad University, Ahmedabad, Gujarat, India Abstract: Over the last decade, there has been growing interest in developing novel nanoparticles (NPs) for biomedical applications. A safe-by-design approach was used in this study to synthesize biocompatible iron oxide NPs. The size of the particles obtained was ~100 nm. Although these NPs were significantly (P<0.05) internalized in MCF-7 (human breast adenocarcinoma cell line) cells, no adverse effect was observed in the cells as assessed by cytotoxicity assays (neutral red uptake and 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide) and cell cycle analysis. Our data demonstrate the potential of iron oxide NPs as a biocompatible carrier for targeted drug delivery. Keywords: biocompatible iron oxide nanoparticles, human breast adenocarcinoma cells, coprecipitation
