A study just published in Nature Communications discovered, thanks to lasers, the mechanisms by which DNA protects itself from sunlight. The study was conducted by a team of researchers at the Institute for Photonics and Nanotechnology under the National Research Council (CNR – IFN, Istituto di Fotonica e Nanotecnologie), the Politecnico di Milano, the Alma Mater Studiorum – Università di Bologna, the Università degli Studi della Tuscia – Viterbo, and Heinrich Heine Universität Düsseldorf.

The study highlighted how DNA is protected from mutations caused by ultraviolet light via its constituent elements, nucleosides. The results, obtained by using extremely short pulses of light, may lead to important applications in nanotechnology and pharmacology, such as fighting skin tumours.
