Nanoparticles – while possessing some amazing properties of strength and power – are also delicate little things, when it comes to manipulating them for use in nanodevices. Many scientists consider that the most promising method of incorporating nanoparticles into functional structures is through their own self-assembly, an approach commonly attempted through different lithography techniques.
