Abstract

Electrolyzed reduced water (ERW) contains a large amount of molecular hydrogen and asmall amount of Pt nanoparticles (Pt NPs). We have found that ERW significantly extended the lifespan of Caenorhabditis elegans in a novel culture medium designated Water Medium.In this study, we found that synthetic Pt NPs at ppb levels significantly extended the nematode lifespan and scavenged reactive oxygen species (ROS) in the nematode induced by paraquat treatment. In contrast, a high concentration of dissolved molecular hydrogen had no significant effect on the lifespan of the nematode. These findings suggest that the Pt NPs in ERW, rather than the molecular hydrogen, extend the longevity of the nematode, at least partly by scavenging ROS.
