TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The self organized medium comprises: reaction compartments for the particle-forming reaction; micelles, normal phase micelles, reverse or inverse micelles, microemulsions, polyelectrolyte/surfactant complexes, organic matrixes, multilamellar vesicles, unilamellar vesicles, lyotropic liquid crystals, lipid-water (l-w) system, lyotropic columnar liquid crystalline materials, lamellar structures, and/or stacks of bilayers; and a system of a surfactant in water or an aqueous solution. The system: comprises a lyotropic structure or a combination of at least two different lyotropic structures; and is in the lamellar phase. The surfactant comprises a nonionic surfactant. The particle having a controllable anisotropic property comprises: semiconducting nanoparticles; a bivalent salt, where the bivalent salt is cadmium sulfide, lead sulfide, and/or cadmium selenide; and nanorods with an average length less than 80 nm and a diameter of 2-10 nm, where the nanorods are cadmium sulfide nanorods. The anisotropic property comprises the anisotropic shape, and the ratio of slenderness (length/diameter). The particles are used as quantum dots in a liquid crystal. Preferred Method: The particle forming reactants comprise a bivalent metal ion in a solution and an inorganic anion in a solution, and the particle forming reaction is conducted within a flow-reactor. The flow rate of the flow-reactor reactor is used to control the anisotropic property. The particle forming reaction is conducted with a stirrer. The rotation speed of the stirrer is used to control the anisotropic property. EXAMPLE - A Synperonic A7 (RTM: Surfactant) and cadmium nitrate solution (10 mM) were mixed together with a ratio of 70-30% and the mixture was poured to the top of the flow reactor. The flow rate of the surfactant solution was 0.5 cm3/seconds in the reactor. The flow rate of the 2% ammonium-sulfide reagent was set to a 20% fractional amount of the reagent. The manifestation of cadmium sulfide particles in this procedure indicated individual nanoparticles with a diameter size of 50-250 nm.
