Abstract
Curcumin associated poly(allylamine hydrochloride) cross-links with dipotassium phosphate and subsequently is assembled with ∼24 nm SiO2 nanoparticles to form hierarchically ordered nanocapsule structures, which are 100–1000 nm in size depending on the concentration of dipotassium phosphate. These structures reverse the excited state intra-molecular hydrogen transfer in curcumin depending on the size of the nanocapsules.

The solution was centrifuged and washed three times in deionized water and dispersed in 3 mL of water for further characterization and investigation. Due to their overall net positive charge these aggregates of CU–PAH–dipotassium phosphate could assist the assembly of negatively charged silica nanoparticles, which shape into hierarchically ordered nanocapsule structures[19] as illustrated in Scheme 1
