Our innovative analytical technique – depletion zone isotachophoresis (dzITP) – uses an ion- depleted zone as the basis for enrichment and separation of analytes in a microfluidic chip. The depletion zone acts as an electrical barrier that stops negatively charged analytes of interest passing through, accumulating them into narrow zones at the border of the depletion zone according to their unique electrophoretic mobilities. This feature is responsible for the striking enrichment capabilities of our method. dzITP can also act as a filter – analyte zone that can be selectively released simply by changing the voltage.
Our platform: a convenient, user-friendly format for enrichment, separation, and filtering of analytes.
