Abstract
Techniques for replacing nanopores within a nanopore based sequencing chip are provided. A first electrolyte solution is added to the external reservoir of the sequencing chip, introducing an osmotic imbalance between the reservoir and the well chamber located on the opposite side of a lipid bilayer membrane. The osmotic imbalance causes the membrane to change shape, and a nanopore within the membrane to be ejected. A second electrolyte solution is then added to the external reservoir to provide replacement nanopores and to restore the membrane shape. The replacement nanopores can be inserted into the membrane, effectively replacing the initial pore without causing the destruction of the membrane.
