Nanotechnology is the engineering of functional systems at the molecular scale. Over the past few years, nanotechnology has found increasing use in biomedical engineering, environmental engineering, and reservoir engineering. Determining reservoir architecture, establishing fluid-flow trends, and identifying reserve growth potential are some of the important features in geosciences that can be investigated with nanoparticles as a tool. Certain type of nanoparticles ‘magnetic nanoparticles’, present extraordinary chemical and physical properties owing to their tiny size and large surface:volume aspect ratio. There are potential applications of magnetic nanoparticles in petrophysical rock characterization, CO2 sequestration, and being used as tracer agents. Making stable magnetic nanoparticles at different environments is challenging and is the foci of many research lab activities. We present our unique methodology for synthesizing magnetite within polymer nanoparticles dispersions. The ability to synthesize iron oxide inside functionalized polymeric nanoparticles offers an effective approach to prevent nanoparticles agglomeration and the potential to enable ligand grafting. Stabilized magnetic PVAm nanoparticles may provide a unique synthetic approach for further targeted delivery of these nanoparticles.
