Incorporation of DNA into nano-object design provides a unique opportunity to establish highly selective and reversible interactions between the components of nanosystems. Assembly approaches based on the nano-object’s addressability promise powerful routes for creation of rationally designed nano-systems. Our progress in controlling the formation of well defined nano-architectures will be reviewed. By tailoring the design of DNA shell we have demonstrated an ability to control an assembly kinetics, clustering, and phase formation of DNA-capped nanoparticles on surfaces and in bulk. For example, we recently discovered formation 3D assemblies with crystalline long-range order in two-component nanoparticle systems that opens new horizons for building a broad range of metamaterials. The DNA design, assembly schemes and thermodynamic pathway leading the formation of organized nanostrctures will be discussed
