| Research Abstract |
A novel heavy-metal implantation method for living cells using focused ion-beam (FIB) were proposed. We performed Au and As ion doping into living cells by using the FIB implantation method; then intracellular level of adenosine triphosphate (ATP) molecule, which is the energy storing molecule for organisms, was evaluated. The ATP level of the implanted cells was found to be modified compared with that of the non-implanted control cells. Our ion implantation technique may be a more accurate tool to quantitatively elucidate the dose-dependent effects of dopants than the conventional methods.
