1. A method of stabilizing colloidal crystals, comprising:
crystallizing oligonucleotides-functionalized nanoparticles under conditions sufficient to provide crystals having a target crystalline structure, and
contacting the crystals with a cross-linking agent under conditions sufficient to cross-link the oligonucleotides and thereby provide stabilized crystals.
