I recently thought of doing a story involving technology on the Planck scale of measurement, but I can't seem to figure out how to go about applying it.
That is pretty general. Perhaps you could brainstorm a few other elements of the story ... setting, main character, etc. Once you have a few ideas on the table, you may see clever ways to create conflicts between them, which could give you some direction for your technology application.
