Patent attributes
Methods for extracting oil from a multiphasic liquid are provided. The method can comprise: introducing the multiphasic liquid to a plurality of nanoparticles, and allowing oil in the multiphasic liquid to be adsorbed by the polymeric shell. The nanoparticles comprise a core and a polymeric shell. The method can further comprise removing the nanoparticles from the multiphasic liquid, and/or recovering the oil adsorbed by the polymeric shell after removing the nanoparticles from the multiphasic liquid. The multiphasic liquid can comprise oil and water (e.g., oil and sea water, such as sea water in an area of an oil spill), stomach fluid and a food-grade oil (e.g., olive oil, vegetable oil, canola oil, or a mixture thereof), or other multiphasic liquids having an oil component.
