'''Bilayer formation''' is part of the Nanopore Wiki learning path. Bilayer formation is a common preparation step for biological nanopore experiments that place pore proteins into lipid membranes for single-channel recording.


== Core concepts ==
* A stable bilayer separates two electrolyte compartments and supports pore insertion.
* Membrane capacitance, baseline noise, and current jumps help diagnose bilayer quality.
* Protein addition side, concentration, and waiting time affect insertion behavior.
* A single-pore state should be confirmed before quantitative sensing.


== Operational checklist ==
{| class="wikitable np-knowledge-table"
! Step
! Description
|-
| 1
| Clean the chamber, aperture, electrodes, and solutions.
|-
| 2
| Prepare lipid and buffer under documented conditions.
|-
| 3
| Form the bilayer and confirm low-noise stability.
|-
| 4
| Add pore protein and wait for a discrete insertion event.
|-
| 5
| Record open-pore current before adding analyte.
|}


== Typical applications ==
* Biological nanopore sensing.
* Single-channel electrophysiology teaching.
* Pore engineering validation.


== Common pitfalls ==
* Mistaking membrane rupture or multiple insertions for a stable single pore.
* Skipping blank recordings after bilayer formation.
* Using unstable membranes for quantitative comparisons.
