[3dem] Glow Discharging of commercial graphene grids

[Henning Stahlberg]

Hi Bob,

Glow-discharging doesn’t work on graphene. But other methods work, some of them even preserve the properties of pristine graphene, such as the very high (ballistic) electric conductivity and the extreme the stability of graphene. One of these is dipping into pyrene, as Radosav Pantelic described here:

Hi Bob,
I was once curious about the graphene grid for my lipid monolayer assay, never tried it out but I guess if you coat the grid with lipid of polar head group, then it becomes easier to absorb your protein of interest.
Hope this help,
Jing

Does anyone have experience with commercially made graphene supported Quantifoils? Specifically if one has to plasma clean to create hydrophilic surface and what gas they use to generate the plasma?
