'''Biological nanopores''' is part of the Nanopore Wiki learning path. Biological nanopores are protein or macromolecular pores that provide reproducible nanoscale sensing structures.


== Core concepts ==
* Examples include alpha-hemolysin, MspA, CsgG, and engineered pore variants.
* Their defined structures enable precise sensing regions and mutation engineering.
* They often require membranes, suitable buffers, and careful protein handling.
* Commercial sequencing pores combine pore proteins with motors and integrated flow cells.


== Selection logic ==
{| class="wikitable np-knowledge-table"
! Step
! Description
|-
| 1
| Define whether the target is DNA, RNA, protein, peptide, or small molecule.
|-
| 2
| Match pore constriction, charge environment, and stability to the target.
|-
| 3
| Check available mutations, adapters, or recognition sites.
|-
| 4
| Validate insertion, single-pore state, and target-specific events.
|}


== Typical applications ==
* Nanopore sequencing.
* Single-molecule recognition and biosensing.
* Mechanistic studies of pore-analyte interactions.


== Common pitfalls ==
* Assuming a pore optimized for sequencing is ideal for every sensing task.
* Ignoring protein storage, membrane composition, and insertion side.
* Over-interpreting rare events without controls and repeats.
