"self-assembled cavity integrated into larger self-assembled components for routing light in optical chip... atomic dimensions enabled by self-assembly with conventional semiconductor scalability... 2 halves of silicon structures are suspended on springs, Casimir force attracts them and van der Waals force sticks them together, resulting in self-assembled resonator with bowtie-shaped gaps surrounded by silicon mirrors... self-assembled photonic resonators for use in electronics, nanorobotics, sensors, quantum technologies"
