Abstract: The present disclosure relates to a method of printing multi-nanoparticles using evaporation dynamics and surface energy control, the method includes: a step S1 of forming a pattern on a surface of a substrate by irradiating ultraviolet rays to a portion of the surface through a photomask; a step S2 of coating the substrate with a solution containing nanoparticles; and a step S3 of lowering surface energy of the coated nanoparticles.
