Graphene (or graphene oxide) is a special form of carbon that has incredible strength, conductivity and flexibility. Applications for mobile phones, computers, wearables and medical devices are foreseen using graphene once it’s available in commercial quantities. But a recent study at the University at California Riverside point out that graphene is extremely mobile in water systems making for a significant risk in spill situations. Other studies have suggested graphene may be toxic so this is definitely an issue should graphene go into widespread use.
The good news is that this risk has been identified early and not long after graphene was in use (think asbestos). This gives us time to better understand the material and how it can be used safely.
