Experimental workflows

Patch-clamp and single-channel electrophysiology concepts are relevant to nanopore measurements. Source: Wikimedia Commons, CC BY-SA 4.0.

Experimental workflows is part of the Nanopore Wiki learning path. Nanopore experiments require coordinated control of sample quality, buffer chemistry, pore or membrane state, electrical recording, metadata, and analysis.

Core concepts

• A useful SOP includes acceptance criteria and troubleshooting logic, not only steps.
• Blank controls and pre-sample baselines are essential for interpreting events.
• Metadata must record voltage, buffer, pore, sample, bandwidth, sampling rate, and time points.
• Real-time judgement prevents poor traces from becoming misleading datasets.

Standard workflow

Step	Description
1	Define the target, question, pore system, and platform.
2	Prepare sample, buffer, blank controls, and recording setup.
3	Verify baseline and pore state before adding sample.
4	Record data while monitoring event frequency, drift, and pore stability.
5	Save raw data, metadata, scripts, and failure notes.

Typical applications

• Custom nanopore sensing.
• Sequencing library preparation and run monitoring.
• Training new laboratory members.

Common pitfalls

• Running samples without blank baselines.
• Changing buffer or voltage without documenting it.
• Keeping only successful traces and discarding failure context.
