1. A system for analyzing molecules, the system comprising:
a sequencing chip comprising an array of cells, wherein a plurality of the cells of the array each comprise a well that is covered by a membrane that encloses a first electrolyte solution having a first osmolarity within the well, the membrane comprising a nanopore;
a reservoir coupled to the sequencing chip, the reservoir comprising a second electrolyte solution having a second osmolarity; and
a processor or a circuitry configured to:
flow the second electrolyte solution from the reservoir over the membrane covering the well, wherein the second osmolarity differs from the first osmolarity, thereby resulting in a first net transfer of ions between the first electrolyte solution and the second electrolyte solution through the nanopore in the membrane; and
apply a voltage across the membrane covering the well, wherein the voltage causes a second net transfer of ions between the first electrolyte solution and the second electrolyte solution through the nanopore in the membrane, wherein the first net transfer of ions and the second net transfer of ions substantially counterbalance each other.
