In this article, we describe the analysis of aptamers for Hg2+ ions through CE with LIF (CE‐LIF) detection using 2% poly(ethylene oxide) solutions containing OliGreen (fluorophore). In the presence of an EOF, DNA strands migrating against the EOF were detected at the cathode end. Four DNA strands – T33, T5C28, T5C5T23, and T15C5T13 – could not be separated through CE‐LIF in the absence of Hg2+. At...
