  • Method and apparatus to separate molecules according to their mobilities
    Patent number: 7579149
    Abstract: A method and apparatus for separating molecules comprises placing different kinds of molecular species onto a probe; and introducing an electric field between the probe and a surface in proximity with the probe so that the different kinds of molecular species may be separated, wherein the different kinds of molecular species have differing mobilities, and wherein the different kinds of molecular species may be separated according to their differing mobilities, such that molecular species that have different mobilities migrate along the probe at different speeds towards the surface. The molecular species may comprise molecules. Alternatively, the molecular species may comprise molecular assemblies, wherein the molecular assemblies may comprise at least one of cells, bacteria, and viruses.
    Type: Grant
