Title: Analyzing the transport of plasmonic particles through mineral formations

Abstract: A transport of plasmonic particles through a mineral formation is analyzed by flowing a plasmonic particles solution through an immobile phase (e.g., a mineral formation), determining an absorbance of the plasmonic particles solution subsequent to flowing the plasmonic particles solution through the immobile phase, comparing the determined absorbance of the plasmonic particles solution with an absorbance of the plasmonic particles solution determined previous to flowing the plasmonic particles solution through the immobile phase, and determining an absorbance of the plasmonic particles to the immobile phase as a function of the comparison. The plasmonic particles solution may be produced by dissolving or suspending plasmonic particles in a mobile phase. Flowing the plasmonic particles solution through the immobile phase may include injecting the plasmonic particles solution into the immobile phase, and then flushing the plasmonic particles solution through the immobile phase.
