'''Electrophysiology''' is part of the Nanopore Wiki learning path. Electrophysiology provides the low-noise electrical measurement framework used by many single-pore nanopore experiments.


== Core concepts ==
* A voltage clamp can hold transmembrane voltage while measuring current.
* Single-channel recordings require stable membranes, clean electrodes, shielding, and low-noise amplifiers.
* Current traces contain baseline current, event signals, drift, and noise components.
* Metadata such as voltage, bandwidth, sampling rate, temperature, and buffer must be recorded.


== Measurement workflow ==
{| class="wikitable np-knowledge-table"
! Step
! Description
|-
| 1
| Prepare the chamber, electrodes, buffer, and shielding.
|-
| 2
| Form or verify a membrane or chip-supported pore system.
|-
| 3
| Measure baseline current and RMS noise before adding sample.
|-
| 4
| Record events and annotate changes in voltage, sample addition, and pore state.

== Typical applications ==
* Biological nanopore recordings.
* Single-channel sensing and pore engineering.
