Resistance of graphene dispersion

Hi,

I just got a small bottle of graphene dispersion (not GO) on ebay and put a small drop on a ciruit board as shown in the pic. I expected to measure a finite resistance because graphene is a conductor as much as I know. But it seems to have zero conductance from what I read on the multimeter. My question is: Why does it have zero conductance? Do I have to do a processing on the dispersion before it starts to be a good conductor?

Thanks in advance...

It's not a conductor if there are gaps; you would need a continuous piece of graphene, or multiple pieces that are bonded together so that they conduct from one to the next.

Here is a commercial supplier, with some helpful notes:
