Abstract

A method of preparation of a 2-D array of particles comprising: mixing the particles and a first liquid, the first liquid having the properties of being soluble in water and reducing surface tension of a water surface; adding the mixture to the water surface; and transferring the 2-D array onto a solid surface. A composition comprising: a 2-D array of particles; and a polymer substantially enveloping the 2-D array of particles.
