What is the exciton Bohr radius? I understand that the exciton is the paired distance of an electron and hole. How does the Bohr radius play a role in this?

The Bohr radius can be calculated for the Hydrogen atom. To make the translation to an exciton, replace the effective mass by the effective mass of the electron and hole.

So for a quantum dot, how can the nanoparticle be smaller than the exciton Bohr radius?
