Energy Emulation

So, i can basically imitate the nature of the energy in question?

A question that's been on my mind for a while since learning about characters like Bishop from the X-men. Considering he seems to have no limit to absorbing energy, it makes me wonder if he or others like him could absorb antimatter. Adding to that, could a bio-energy manipulator be able to control antimatter by altering their biofield? Could they emulate antimatter or copy its properties?
