We recently reported that a great variety of DNA oligonucleotides (ONs) used as chiral selectors in partial‐filling capillary electrophoresis (CE) exhibited interesting enantioresolution properties toward low‐affinity DNA binders. Herein, the sequence prerequisites of ONs for the CE enantioseparation process were studied. First, the chiral resolution properties of a series of homopolymeric sequences...
The development of the systematic evolution of ligands by exponential enrichment (SELEX) process has allowed the isolation of oligonucleotide sequences (referred as aptamers) with the capacity to recognize various classes of target molecules with high affinity and specificity. At the present time, various analytical aptamer-based formats have been developed as suitable tools for the detection and...
A chemometric methodology was proposed to optimize the migration time, height equivalent to a theoretical plate and separation of a mixture of a series of imidazole compounds by capillary electrophoresis. The optimization process was based on a special polynomial from 9 or 18 preliminary experiments. This method connects a general simplex method to a computer. A simplex two or three optimization-capillary...
