Challenge: Oil spill contamination cannot be cleaned rapidly and completely from varied environments. Technology: Ferrofluids are colloidal dispersions of magnetic nanoparticles that can be manipulated with an external magnetic field. This invention proposes to apply ferrofluidic principles to the mitigation of oil contamination of solids (wetlands) water surfaces and water sub-surfaces. The particle size surfaces and dispersants can all be optimized for stabilizing oil removal collectability and water purification.
1) This method has the potential for rapid development and deployment. 2) Allows for the capture of oil from contaminated surfaces remotely without direct contact with the surface.
