As described in the paper, a new method for the fabrication of sandwich-like inverse opal devices was developed. Mono-dispersed particles are firstly assembled between two parallel substrates by taking advantage of capillary forces and rheological forces. Then a liquid precursor is infiltrated into the voids between the substrates. The following hydrolysis and calcination give rise to the inverse opal with interconnected voids.
