ABSTRACT:
The present invention provides method and apparatus for manipulating one or more chemicals within a reaction chamber or housing by dielectrophoretic forces. At least two materials, one of which is a chemical to be manipulated, are provided within the housing. The materials have different dielectric constants. A non-uniform electrical field is applied to the materials within the housing and, as a result of dielectrophoretic forces generated by the applied field, the relative positions of the materials are varied. Accordingly, a chemical can be selectively manipulated to different positions within the housing as, for example, to a catalyst or chemical analyzer located within the housing. The present apparatus may also be used to simultaneously manipulate more than one chemical to mix, or induce a chemical reaction, between the different chemicals in the housing.
