ABSTRACT:
The present invention relates to a novel, small-scale, electrophoretic separation system based on photodefined polymers and electrode-defined sample injection. Diffusion and displacement coefficients may be modified by varying the gel concentration, the intensity of the incident UV radiation and the temperature at which the gel is run. The device is an major advance over current technology since it provides for a significant reduction in size of the micro-electrophoresis apparatus and a significant cost savings.
