However, chemical and spatial details of them are not known. We have developed a method-ology for estimating localization of AP sites using Förster resonance energy transfer (FRET). We have already found that carbon ion can produce clustered DNA dam-age regions within a track using dry DNA film as an irra-diation sample by the FRET methodology. We applied the methodology to a cell-mimetic buffered DNA solu-tion irradiated with carbon ion beam with LET of ~90 keV/micron As a result, we found that the carbon ion tends to produce more clustered AP sites compared with 60Co gamma-rays., H28年度HIMAC共同利用研究成果発表会}, title = {重粒子線によるDNA損傷形態に関する研究}, year = {2017} }
