Abstract: Heavy ion beam biology is a jumped-up scientific subdivision.China acquired a series of prior achievements and for the first time brought forward the idea that heavy ion biological effects are the integrated results of the four effects, i. e. energy deposition, mass deposition, charge exchange and momentum transfer. Researchers have validated the mass deposition process in small biomolecules and pharmic molecules induced by heavy ion implantation, and researches on modification of biomolecules and pharmic molecules by heavy ion implantation have been taken up. In the near future stable and radioactive heavy ion beams can be used to implant biomoleules and pharmic molecules, thereafter X-ray diffraction analysis, electron microscopic autoradiography and image processing can be used to make further studies on mass deposition induced by heavy ion implantation.
