Imaging electrophoresis system

A method for identifying analyte molecules in a sample comprising:

• providing an evanescent field imaging ellipsometry apparatus for creating an evanescent field above a surface of a bioarray having an array of probes which probes will be in the evanescent field and for spatial detection of binding events in the array with analyte molecules in a sample:
• providing an electrophoresis apparatus for establishing an electrophoresis functioning electrical field extending in a direction laterally disposed to the bioarray and for placing a sample for moving analytes within the sample selectively by electrophoresis functioning laterally across the bioarray;
• causing the sample to be exposed to the electrophoresis field whereby analyte molecules will transit within the electric field separated by the effect of the electric field;
• selectively temporally detecting binding events of molecules that are moved by electrophoresis functioning across the bioarray.
