title: A multichannel electrophoresis microchip platform for rapid chiral selector screening.
abstract: This study presents a four-channel electrophoresis chip platform, featuring double-cross hydrostatic sample injection, for rapid chiral selector screening. This platform needs only five electrodes to drive microchip electrophoresis in four separate channels for screening four chiral selectors at a time. To demonstrate the performance of this screening platform, eight neutral CDs and their derivatives as chiral selectors were screened towards two FITC-labeled chiral compounds. The screening could be accomplished in less than 2 min. Dimethyl-beta-CD and hydroxypropyl-alpha-CD was demonstrated to be the appropriate selectors for FITC-norfenefrine and FITC-baclofen, respectively. The established platform is easy to operate and suitable for rapid screening process, which is expected to be a potential platform for high-throughput screening of chiral selectors.
