The invention discloses methods for making micron/nano meter sized particles of various inorganic materials such as minerals/oxides/sulphides/metals/ceramics at a steadily expanding liquid-liquid interface populated by suitable surfactant molecules that spontaneously organize themselves into superstructures varying over large length-scales. This experiment is realized in a radial Hele-Shaw cell where the liquid-liquid interfacial growth rate and consequently time scales such as arrival of surfactant molecules to the interface, the hydrodynamic flow effect to modulate the material organization into super structures at the dynamic charged interface.
