Since the transparent SiO₂ nanoparticle aggregate film with a nanoporous network allows a polymer or dye solution to penetrate well, it is possible to embed a micro-optical structure such as a WGM microcavity laser inside the film by a printing method such as inkjet. In other words, it can realize an optical integrated circuit as if “drawing on paper”. More information can be found in article number 2200018 by Hiroaki Yoshioka and co-workers.
