The reaction occurs at the bottom of the ZMW, presumably against glass or something else transparent. The hole is to narrow for it to go back up into the solution, so it just escapes out the bottom. The video sensors are facing the bottoms of the holes (not embedded within them), according to my interpretation of their promotion videos.
