title: Portable capillary electrophoresis system with potential gradient detection for separation of DNA fragments.
abstract: A portable capillary electrophoresis (CE) system with a novel potential gradient detection (PGD) was utilized to separate DNA fragments. For the first time it was demonstrated that separation of DNA fragments in polymer solution could be detected by a portable CE system integrated with PGD, with a limit of detection (LOD) comparable to that of the CE-ultraviolet (UV) method. Effects of buffer solution, sieving medium, and applied voltage were also investigated. The portable CE-PGD system shows several potential advantages, such as simplicity, cost effectiveness, and miniaturization.
