Since the concept of miniaturized total analysis systems (microTAS) was invented, a great number of microfluidic devices have been demonstrated for a variety of applications. However, an important hurdle that still needs to be cleared is the connection of a microfluidic device with the rest of the world, which is often referred to as the macro-to-micro interface, interconnect, or world-to-chip ...

Advances in many areas of genomics research are heavily rooted in engineering technology, from the capillary electrophoresis units used in large-scale DNA sequencing projects, to the photolithography and robotics technology used in chip manufacture, to the confocal imaging systems used to read those chips, to the beam and detector technology driving high-throughput mass spectroscopy. Further ad...

Microfluidics, an enabling and emerging technology in cancer metastasis research, has yet to be applied in the analysis of individual cells taken directly from patient carcinomas. Accordingly, we have developed an integrated microfluidic methodology to label, dissociate, transport and detect patient-derived tumour cells. Following on-chip cold perfusion of tissue with antibody and enzymes, fluo...

Our single cell analytical experiments for future protein fingerprinting combines microfluidic on-chip protein electrophoresis with latest laser technology for single cell manipulation and (label-free) protein detection, and is presented by the following issues: 1) Single cells were trapped and navigated by optical tweezers (OT) in a PDMS microfluidic device, and lysed at a predefined position....

Most of the materials used in the industry of aero-engine components generally consist of titanium alloys. Advanced materials, because of their excellent combination of high specific strength, light weight and general corrosion resistance. In fact, chemical wear resistance of aero-engine alloy provides a serious challenge for cutting tool material during the machining process. The reduction in ...

The most common technique for sorting, identifying, and purifying nucleic acid fragments is agarose gel electrophoresis. performance of the electrophoresis could be impacted by buffers’ composition, ionic strength, pH characteristics [1].

Isoelectric focusing (IEF) is a powerful and widely used technique for protein separation and purification. There are many embodiments of microscale IEF that use capillary or microfluidic chips for the analysis of small sample volumes. Nevertheless, collecting the separated sample volumes without causing remixing remains a challenge. Herein, we describe a microfluidic Slipchip device that is ab...
