A method of preparing a nanoparticle having a particle size of 1 nm to 1 μm, said method comprising continuously supplying a solution containing a particle-forming precursor into a micro channel having a diameter of 1 μm to 1 mm, said micro channel being disposed in a heating zone. The solution is heated rapidly up to a reaction initiation temperature to cause a reaction in said solution. The solution is rapidly cooled to prepare the nanoparticle. |
