3D colloidal crystals of bi-directional modulation have been fabricated via two steps: (1) the modulation of the sphere interstice in each layer depends on the process of modified microcontact printing (mCP); (2) the layer spacing of the 3D colloidal crystal is determined by the in situ layer-by-layer photopolymerization technology (LBLP). The versatility of this method has been demonstrated by the integration of colloidal spheres with different diameters or patterns.
