Abstract

This report describes a miniaturized size exclusion chromatography column that effectively preseparates raw samples for medical point-of-care testing (POCT) devices. The minicolumn is constructed of polydimethylsiloxane fabricated on a glass slide. The minicolumn separates 300 ng/ml of beta-human chorionic gonadotropin (Β-hCG) from an immunoglobulin G (IgG)-rich solution (100 μg/ml) in 7.7 min, with 2.23 resolution and 0.018 mm plate height. The complete analyte discrimination shows potential for the sample preparation stage of POCT devices for cancer screening, prognosis, and monitoring.
