Definition
When an external electric field is applied to liquid solutions in nanochannels, electrically suspended charged particles and molecules start to move relative to the stationary liquid (electrophoresis). The ionized liquids also flow in the nanochannels in the presence of the external electric field (electroosmosis). The final motion of nanoparticles in the nanochannels, which is affected by both the electrophoretic effect and the electroosmotic flow field, is called the electrokinetic motion of the particles in the nanochannels.
Chemical and Physical Principles
Nowadays, with recent advancements in nanofabrication technologies, there has been a growing interest in developing nanofluidic devices involving the nanoparticles (e.g., nanofluidic devices for DNA studies and nanofluidic sensors for detecting aerosol nanoparticles). The electrokinetic effects in nanochannels completely behave differently from those in...
