Abstract
Compositions containing a transporter component and a signaling component and a method for using said compositions for analyzing porous media and flowing liquid streams, specifically for measuring pressure, temperature, relative abundance of water, pH, redox potential and electrolyte concentration. Analytes may include petroleum or other hydrophobic media, sulfur-containing compounds. The transporter component includes an amphiphilic nanomatenal and a plurality of solubilizing groups covalently bonded to the transporter component. The signaling component includes a plurality of reporter molecules associated with the transporter component. Said reporter molecules may be releasable from the transporter component upon exposure to at least one analyte. The reporter molecules may be non-covalently associated with the transporter component, or the reporter molecules are covalently bonded to the transporter component. Furthermore, said compositions and methods may be used to actively enhance oil recovery and for remediation of pollutants.
