Capillary Action
Capillary Action — The ability of a liquid to flow in narrow spaces against gravity, relevant to microfluidic peptide synthesis and diagnostic devices.
What Is Capillary Action?
Capillary action is the spontaneous flow of liquid through narrow spaces driven by adhesive and cohesive forces. In peptide research, capillary action is the principle behind capillary electrophoresis sample injection, thin-layer chromatography, lateral flow immunoassays, and the wicking of solvents through resin beds during gravity-flow chromatography.
Applications
- Lateral flow assays: Rapid peptide/protein detection (pregnancy tests, COVID tests) driven by capillary flow
- Western blot transfer: Capillary transfer uses wicking to move proteins from gel to membrane without electricity
- Microfluidics: Capillary-driven peptide assays in lab-on-a-chip devices
