Gordon and Sweets method uses which reagent?

Explanation:
Gordon and Sweets is a silver impregnation method used to visualize reticular fibers, which are delicate, argentophilic structures in tissues like liver, bone marrow, and lymphoid organs. The essential reagent that makes this technique work is a diamine silver solution; it impregnates the fine reticular network so that, after reduction, the fibers appear as dark deposits against the counterstain. Iodine, pyronin, and acid fuchsin are not the silver impregnation reagent in this method—they’re used in other stains or as counterstains in different protocols.
