I have come across use of the terms cis and trans electrodes in the context of nanopores and driving charged biomolecules through a pore using an electric field :
FIG. 1. Drawing of the cis negative electrode and trans positive electrode chambers. The arrows show the direction of electric field lines. The pore diameter $d$ and length $l$ and the capture radius $r$ are also shown.
I wondered what the origin of the term is.
I know about cis and trans isomers, but I have not come across the term before in terms of electrodes. Is there a simple explanation?
I can just assume that cis/trans are just another terms for cathode and anode, but I think I am missing something. If the cis electrode is the cathode and the trans electrode is the anode, then why not just call them that? Is there any additional meaning?
