Enhanced retention or solubilization of a contaminant may be helpful in a remediation setting. Nanomaterials may be useful in decreasing sequestration of hydrophobic contaminants, such as Polycyclic aromatic hydrocarbons (PAHs), bound to soils and sediments [4]. The release of these contaminants from sediments and soils could make them more accessible to in situ biodegradation. For ex- ample, nanomaterials made from Poly (ethylene) Glycol modified Urethane Acrylate have been used to enhance the bioavailability of Phenanthrene.
