1. A method for scale treatment comprising:
providing a treatment fluid comprising:
metal-organic cages, wherein each metal-organic cage comprises a single pore; and
a base fluid;
contacting an inorganic scale with the treatment fluid; and
dissolving at least a portion of the inorganic scale through capture and sequestration of cationic components of the inorganic scale in pores of the metal-organic cages in the treatment fluid.
