“…Previous studies indicated that light promotes PSs to an excited state, after which electrons (or energy) are transferred to molecules such as molecular oxygen, forming reactive oxygen species (ROS) ( Fig. S1b and (Feuerstein, Ginsburg, Dayan, Veler, & Weiss, 2005;Liang et al, 2013;Lubart et al, 2011;Malik, Hanania, & Nitzan, 1990;Marugán, van Grieken, Pablos, & Sordo, 2010)). Increased ROS levels can cause damage to cellular proteins, lipids, and DNA (Farr & Kogoma, 1991;Feuerstein, Moreinos, & Steinberg, 2006;Liang et al, 2013;Lipovsky, Nitzan, Friedmann, & Lubart, 2009;Lipovsky et al, 2010).…”
