    摘要： A microfluidic chip formed with multiple fluid channels terminating at a tapered electrospray ionization tip for mass spectrometric analysis. The fluid channels may be formed onto a channel plate that are in fluid communication with corresponding reservoirs. The electrospray tip can be formed along a defined distal portion of the channel plate that can include a single or multiple tapered surfaces. The fluid channels may terminate at an open-tip region of the electrospray tip. A covering plate may substantially enclose most portions of the fluid channels formed on the channel plate except for the open-tip region. Another aspect of the invention provides methods for conducting mass spectrometric analysis of multiple samples flowing through individual fluid channels in a single microfluidic chip that is formed with a tapered electrospray tip having an open-tip region.

    摘要： A microfluidic device is provided with appropriate integrated structures to conduct large volume PCR and end-point or real-time capillary electrophoresis detection. The microfluidic device includes a substrate having an amplification chamber of a volume of nucleic acid, wells disposed on the substrate, flow channels connecting the wells and the chamber in the substrate to allow for solution flow through the chamber, and one or more separation channels provided in the substrate and connected to the chamber for separating and detecting a fraction of the amplified nucleic acid. The chamber, the flow channels, and the one or more separation channels are configured such that the hydrodynamic flow resistance of the chambers and the flow channels combined is at least 10Λ3 times smaller than the hydrodynamic flow resistance in the one or more separation channels. The microfluidic device can achieve a very high sensitivity in detection while being highly cost effective.

    摘要： The invention herein provides improved sample injection systems and related methods to create microfluidic devices with symmetrical channel configurations that can produce relatively large sample volumes. An embodiment of the invention provides microfluidic structures with different geometries that are symmetrical from the perspective of a sample load channel and a sample waste channel, which essentially eliminates issues of time offset and other problems commonly associated with twin-T sample formation techniques. A split-injection approach and related methods of sample plug formation are therefore provided.
