Abstract
Suspensions comprising amphiphilic nanoparticles and at least one carrier fluid. The amphiphilic nanoparticles may be formed from a carbon-containing material and include at least a hydrophilic portion and a hydrophobic portion. The hydrophilic portion comprises at least one hydrophilic functional group and the hydrophobic portion includes at least one hydrophobic functional group. Methods of forming the flooding suspension and methods of removing a hydrocarbon material using the flooding suspensions are disclosed.
