Image for: Ultrafast lasers can protect a DNA building block from light-induced dissociation


When the adenine molecule is ionised by VUV radiation it undergoes dissociation, however by taking advantage of a charge migration mechanism and by properly timing a second infrared laser pulse it is possible to stabilise it via a second ionisation event.
