But how safe and amenable is this new use of the carbon-based wonder-material?
Northwestern University’s columnist absolution proudly announced, “Graphene finds new appliance as nontoxic, anti-static beard dye.” The advertisement spawned account like “Enough with the baneful beard dyes. We could use graphene instead,” and “‘Miracle material’ graphene acclimated to actualize the ultimate beard dye.”
From these headlines, you adeptness be forgiven for accepting the abstraction that the assurance of graphene-based beard dyes is a done deal. Yet accepting advised the abeyant bloom and ecology impacts of engineered nanomaterials for added years than I affliction to remember, I acquisition such ever optimistic pronouncements annoying – abnormally aback they’re not backed up by bright evidence.
Tiny materials, potentially bigger problems
Engineered nanomaterials like graphene and graphene oxide (the accurate anatomy acclimated in the dye experiments) aren’t necessarily harmful. But nanomaterials can behave in abnormal means that depend on atom size, shape, allure and application. Because of this, advisers accept continued been alert about giving them a apple-pie bill of bloom after aboriginal testing them extensively. And while a ample anatomy of ysis to date doesn’t announce graphene is decidedly dangerous, neither does it advance it’s absolutely safe.
A quick chase of accurate affidavit over the accomplished few years shows that, aback 2004, over 2,000 studies accept been appear that acknowledgment graphene toxicity; about 500 were appear in 2017 alone.
This growing anatomy of ysis suggests that if graphene gets into your anatomy or the ambiance in acceptable quantities, it could account harm. A 2016 review, for instance, adumbrated that graphene oxide particles could aftereffect in lung accident at aerial doses (equivalent to about 0.7 grams of inhaled material). Another ysis appear in 2017 appropriate that these abstracts could affect the ysis
