Well, bouyancy doesn't really make sense at a molecular level. The closest explanation would be the same reason you don't fall through your chair: electromagnetic interactions between the atoms of the molecules in your body/clothing are repelled once they get close enough to other nuclei.

Bouyancy is a property of fluid pressure, which at a molecular level is indistinct from any other two objects colliding. Bouyancy only makes sense on a larger scale, because otherwise WHERE the particles are isn't really relevant.
