Is there a way I can visualize curcumin in mice tissues (for example after subcutaneous administration of a curcumin formulation) employing some sort of specific stain for curcumin or polyphenol or similar? Employing autofluorescence of curcumin is hampered by tissue autofluorescence. And I think employing the usual staining methods for lipids or phenols would stain non-specific lipidic or proteinic regions of the tissue.
