A large-area monolayer of solvent dispersed nanomaterials and method of producing same is provided. The method includes dripping a nanomaterial solvent into a container filled with water whereby the nanomaterial being dripped collects at the air-water interface to produce the large-area monolayer. In one embodiment, different nanomaterial solvents can be dripped, at predetermined intervals such that the resulting large-area monolayer includes at least two different nanomaterials.
