we can "see things" in different ways other than with our eyes,
like with this structure
http://en.wikipedia.org/wiki/Tevatron_collider
we can see the results an object has on others. with that I'd say
a quark
its basically a part (3 of them) within a proton and/or neutron of an atom
http://www.physics.usyd.edu.au/hienergy/probing_structure.html
with our eyes and other equipment directly I'd say
an electron, or the "cloud" it forms around an atom
Cern is building a new particle accelerator that will result in witnessing even smaller particles next year I believe

It is impossible to observe the smallest object without special microscope.
The smallest particle of the Universe cannot be shadowed and is basically invisible ,and that would be dark matter.

"Seen" is a relative term.
Our eyes can see a human ovum just barely without a magnifying lens.
Optical microscopes can barely "see" subcellular structures like mitochondria.
Electron microscopes can "see" large macromolecular structures like the pores of the nuclear membrane of cells.
Atomic force microscopes can "see" individual atoms.
A detector like a geiger counter can "see" subatomic particles like beta particles.
High energy physicists regularly "see" particles that are the building blocks of matter, known as quarks.
And lastly, when fully dark adapted, the photoreceptor cells of our eyes can really see individual photons, which are massless particles of light. Although, remember that a photon is not an object per se.
So I guess the answer would be "photons" if you are asking about seeing biologically, and "quarks", if you are asking about detecting with man made equipment.

It depends on the quality of our eys, our glasses and our microscopes.
I think modern physics has discovered paricles very much smaller than the electron. But to say that this objects have been seen is not correct.

Actually seen? A proton (subatomic particle), I believe. There are smaller particles (quarks etc) but I don't think anyone has actually seen them - their presence is inferred rather than known.

An atomic particle. Technically, when you look at any one thing, you are looking at gazillions of atoms, so there you go.

well the atom is small and nuclear bofs must have seen it, otherwise it could be my bank account

IBM has electron microscopes which can see individual atoms.
