Femtosecond-laser-written optical waveguides were monolithically integrated into a commercial lab-on-a-chip to intersect a microfluidic channel. Laser excitation through these waveguides confines the excitation window to a width of 12 μm, enabling high-spatial-resolution monitoring of different fluorescent analytes, during their migration/separation in the microfluidic channel by capillary elec...
We present a compact portable chip-based capillary electrophoresis system that employs capacitively coupled contactless conductivity detection (CD) operating at 4 MHz as an alternative detection method compared to the commonly used optical detection employing laser-induced fluorescence. The disposable chip for this system is fabricated out of PMMA using injection molding; the electrodes are scr...
The development of miniaturised devices for genetic diagnosis is of great interest for medicine applications. In this paper, we focus on the design, the experimental technology and characterization of a new silicon micro-bio-chip for rapid testing of DNA material. This chip integrates two classical processes for DNA analysis: polymerase chain reaction – PCR – technique for fragments amplificati...
This review summarizes the advancement in operational modes and selected applications of the title technique over the past five years. Regarding operational modes particular emphasis is put upon increasing selectivity and resolution, hyphenation of capillary electrophoresis with techniques based on other than electromigration principles, the so-called chip technology and new ways of detection. ...
Researchers in molecular biology spend a significant amount of time tending to the staining and destaining of electrophoresis gels. Here we describe a simple system, costing approximately $100 and taking approximately 1 h to assemble, that automates standard nucleic acid and protein gel staining protocols. Staining is done in a tray or, with DNA gels, in the electrophoresis chamber itself follo...
