A method for processing nanoparticles using a self assembly mechanism. The method includes flowing a first reactant species through a first channel region, which has a predetermined dimension including a first width and a first depth. The method includes flowing a second reactant species through a second channel region, which also has a predetermined dimension including a second width and a second depth. The method includes outputting the first reactant species through a first orifice exiting the first channel region and outputting the second reactant species through a second orifice exiting the second channel region. Additionally, the method forms an interface region along a first predetermined length in a third channel, which couples the first orifice to the second orifice at the interface region. The method contacts one or more of the first reactant species with one or more of the second reactant species at the interface region to form a combined species of the one or more first reactant species and the one or more second reactant species. The method also transfers the combined species of the one or more first reactant and the one or more second reactant species from the first predetermined length to a second predetermined length of the third channel region.
