Hmm... that idea even upgrades from DIY to a low cost product! How about ink jet printed conductors
with some large lands that spring contacts connect to on your electroporator-with-safety-features?
The paper could come from the clean and pure sources used for old school analytic filter paper.

It could come in sealed sterile packs. Hey Nathan -- want to do some testing of that starting with
hand drawn graphite papers? The extra volume of critters outside the lines may not matter.
For apps where a tiny volume is all you have the paper could be trimmed away just outside the conductive lines
and dip it in a microdrop of bugs to load your bugs into the "zap chamber"

Fantastic lateral thinking Simon!
