1. A nanopore sequencer, comprising:
- a cis well;
a trans well;
a nanopore fluidically connecting the cis well and the trans well; and
a modified electrolyte in the cis well, or the trans well, or the cis and trans wells, the modified electrolyte including an electrolyte and a cation complexing agent;
wherein;
the modified electrolyte is in the cis well, the nanopore sequencer further comprises a non-modified electrolyte in the trans well, and the non-modified electrolyte includes the electrolyte without the cation complexing agent;
orthe modified electrolyte is in the trans well, the nanopore sequencer further comprises the non-modified electrolyte in the cis well, and the non-modified electrolyte includes the electrolyte without the cation complexing agent.

Abstract
Example nanopore sequencers include a cis well, a trans well, and a nanopore fluidically connecting the cis and trans wells. In one example sequencer, a modified electrolyte (including an electrolyte and a cation complexing agent) is present in the cis well, or the trans well, or in the cis and the trans wells. In another example sequencer, a gel state polyelectrolyte is present in the cis well, or the trans well, or in the cis and the trans wells.
