Figure 5. GSH depletion for a range of graphenic carbon materials.

Figure 5

(a) GSH depletion after 2hr incubation as a function of mass dose.

(b) Recasting above data as function of surface area dose, which partially collapses the data to a near-universal curve. Surface areas in (b) by nitrogen vapor adsorption and BET theory except for glassy carbon, which is a non-porous material for which surface area can be estimated from particle size and density.
