Magnetic properties of graphene oxide functionalized with “Au” and “Fe2O3” nanoparticles: A comparative study

by

https://www.sciencedirect.com/science/article/pii/S221478532031659X Abstract Reduced graphene oxide (r-GO) nanocomposites are very useful for different applications such as magnetic storage media and bio-imaging/biomedical applications and recently have been found to be very useful in electronic and magnetic resonance imaging contrast agent where r-GO was functionalized with silica coated gold and iron oxide nanoparticles. The potential material for these different … Read more

Graphene oxide affects in vitro fertilization outcome by interacting with sperm membrane in an animal model

by

https://www.sciencedirect.com/science/article/pii/S0008622317312757#undfig1 Abstract We realized the exposure of boar spermatozoa to graphene oxide (GO) at concentration of 0.5, 1, 5, 10 and 50 μg/mL in an in vitro system able to promote the capacitation, i.e. the process that allows sperm cells to became fertile. Interestingly, we found that the highest GO concentration (5, 10 and 50 μg/mL) are toxic for spermatozoa, while the … Read more
