You may be thinking about neutrinos. Those are particles and, along with photons, the smallest ones currently known.

So far it looks like there is nothing smaller inside an atom than quarks. Our experiments look for evidence that quarks have some sort of shape or structure. If they do have a shape or structure rather than just being a point (which by itself is a very difficult concept to understand), then there might be some sub-quark constituents. At present there is little or no evidence of any structure to the quark.
