No. Expansion happens in regions of space not bound by strong gravitational fields. That means it is happening in intergalactic space (and is limited even within galactic clusters and regions of higher mass density). Not inside atoms, not inside planets, stars, black holes, galaxies.
A dense particle, early universe with expansion from nothing everywhere should of made a universe of particles ....unless it is (''Anti gravity'') dark matter that is itself is expanding and that fuels expansion in certain regions of the universe?
I don't understand your suggestion that the Universe should be made of particles. The general picture of how the early Universe developed very tiny inhomogeneities which then allowed gravitational clumping is well understood. What is expanding is spacetime itself, not matter (dark or otherwise). Part of the "force" involved is dark energy, which has been compared with a type of anti-gravity, but isn't generally considered to be such.
Dark matter doesn't expand- gravitationally, it behaves just like ordinary matter, which is why we can detect it so easily.
