Can positronium fragment complex molecules?

This project aims to explore whether positronium, which is produced in the body during positron emission tomography (PET), can damage DNA. PET scans are used to locate cancer. Positrons produce positronium, a matter-antimatter bound state, in the body during a PET scan. It is known that electrons can damage DNA by forming a transient negative ion that fragments DNA building blocks and it is suggested that positronium could damage DNA in the same way. This work will explore fragmentation of DNA nucleobases by positronium impact. The results of this work may contribute to new models of PET use.
