Graphene is a thinnest element famous to man, a million times thinner than a tellurian hair. Graphene oxide (GO), in turn, is an atomically skinny element consisting usually of CO and oxygen atoms. GO is now being deliberate for countless uses including drug smoothness and other medical applications. However, it is of vicious significance to know how these materials correlate with a body.
In a new investigate led by Professor Bengt Fadeel at the Institute of Environmental Medicine, Karolinska Institutet, it is shown that neutrophils, a many common form of white blood dungeon that is specialised in combating infections, recover supposed neutrophil extracellular traps (NETs) when encountering GO. NETs are done adult of a “spider-web” of DNA flashy with proteins that assistance neutrophils to destroy microorganisms such as germ and fungi. The researchers found that GO causes specific changes in a lipid combination of a dungeon surface of neutrophils heading to a recover of NETs. They could also uncover that antioxidant diagnosis topsy-turvy this process. In a messenger investigate published in Nanoscale, it was shown that GO is degraded in NETs, most like germ and other pathogens.

“Taken together, these studies uncover that GO can be trapped and degraded in NETs only like pathogens. Understanding how a defence complement senses and handles GO paves a approach for safer biomedical applications of GO and other graphene-based materials, for instance in a context of drug delivery”, says Professor Bengt Fadeel.
The stream study, achieved during Karolinska Institutet in partnership with Professor Kostas Kostarelos during a National Graphene Institute, University of Manchester, and a National Center of Imaging Mass Spectrometry during Chalmers University of Technology, is partial of a EU’s largest investigate initiative, a Graphene Flagship Project which has over 150 educational and industrial partners and a sum bill of €1 billion.
