Nanostructured TiO2-induced photocatalytic stress enhances the antioxidant capacity and phenolic content in the leaves of Vitis vinifera on a genotype-dependent manner

Publication date: Available online 20 November 2018Source: Journal of Photochemistry and Photobiology B: BiologyAuthor(s): László Kőrösi, Sakina Bouderias, Kristóf Csepregi, Balázs Bognár, Péter Teszlák, Alice Scarpellini, Andrea Castelli, Éva Hideg, Gábor JakabAbstractOver the past decades, nanotechnology has received great attention and brought revolutionary solutions for a number of challenges in scientific fields. Industrial, agricultural and medical applications of engineered nanomaterials have increased intensively. The ability of titanium dioxide nanoparticles (TiO2 NPs) to produce reactive oxygen species (ROS), when excited by ultra-violet (UV) light, makes them useful for effectively inactivate various pathogens. It is known that ROS also have signalling role in living ...
