SCODAPHORESIS AND METHOD AND APPARATUS FOR MOVING AND CONCENTRATING PARTICLE

摘要

PROBLEM TO BE SOLVED: To apply an alternating drive field and an alternating field that alters mobility of particles in a method and apparatus for moving and concentrating the particles.SOLUTION: In the method, the driving field and mobility-varying field are correlated with one another. The method and apparatus may be used to concentrate DNA or RNA in a medium, for example. The method and apparatus for extracting particles from one medium into another involve applying an alternating driving field that causes net drift of the particles from the first medium into the second medium but no net drift of the particles in the second medium.
