Maybe telescopes someday, any sufficiently important science’s applications is not predictable, see Kroemer’s Nobel lecture on semiconductor heterostructures.
That said, it seems like the immediate application is improved research lab instrumentation to be used for molecular chemistry investigation of small samples, short distances, short times to pick apart biochemical reaction pathways for problematic / poorly understood / interesting reactions ( prions, membranes, …); they cite improvements on “single-molecule Raman and FRET spectroscopy” see https://en.wikipedia.org/wiki/F%C3%B6rster_resonance_energy_transfer#:~:text=FRET%20can%20be%20used%20to,successful%20mixing%20of%20different%20membranes.
Electron microscopes. I forgot about those.
