Do you know why it was thought necessary to incubate the samples for 22 hours before proceeding with phase-contrast microscopy? I assume that these graphene particles (being inert/non-organic), would not require any nutritional support from a growth medium. If that is not what was meant by incubation, maybe the term's usage in this context could be clarified.

In any case, it is extremely bad news if no local anesthetic agents are free of this toxic material.
