    Potentially fascinating applications for these little sensors,

    Are there any 2-D materials in this universe? How would one gauge the potential environmental impact of such a thing if they have been created? How would a genuinely 2-D object interact inside a person?

    Or do they mean "flat", but want to sound higher tech?

    Might be a silly question, but what would immune systems make of theses things - could they cause problems for some people? Also it's all very well detecting pollution but there has to be the political and social will to do something about it.

    They're telling fibs and they're not fooling us.

    2D in this context means the material is a single atom thick. So, yeah, still 3D if you go small enough. But pretty thin by everyday standards :)

    The toxicity issue is still being investigated for different 2D materials (eg, graphene). I guess they will have to do safety trials once they have a gadget, as for any new device intended to work inside the body (pacemaker, stent, hip replacement...).

    If they'd said 1D they might have had a point.
