It is shown that in DNA-like molecules containing added, excess charges, such as electrons and holes (cation-radicals), it is possible by highly energetic, local, mechanical excitation at definite places of the chain to control the creation of breathers/bubbles and hence to control the long-range transfer of charges moving along the chain in a definite given direction with no external electric field needed.
