    摘要: A technique is presented for aligning, in a desired region within a flow chamber of a flow cell, a non-spherical biological entity carried in a sample. The flow chamber has a rectangular cross-section. A bottom flow input module, a top flow input module and a sample input module provide a first fluid, a second fluid, and the sample, respectively, to the flow chamber. The first and the second fluids laminarly flow along a bottom and a top wall of the flow chamber and the sample laminarly flows sandwiched between them. By controlling rate of flow of the first and/or the second fluid the sample flow, and thus the non-spherical biological entity, is focused in the desired region. An acoustic transducer generates a standing acoustic wave having pressure node linearly arranged along an axis passing through the desired region to orient the non-spherical biological entity in the desired region.

    摘要: A method and system for improving throughput of a fluidic system such as a biopolymer analysis system by cleaning accumulated or clogging biopolymer from the fluidic system is disclosed. The method and system utilize a light energy source to photocleave the biopolymer molecules that may accumulate or aggregate in the fluidic system or clog a passageway. The accumulated biopolymer may be exposed to a light energy source for a sufficient period of time such that the biopolymer molecule is dosed with sufficient energy to photocleave the biopolymer molecules, thereby restoring the efficiency of and flow through the system.

    摘要: Methods, devices, and compositions are described that provide for amplification of nucleic acid sequences without reliance upon temperature cycling, thus freeing the methods from conventional benchtop thermal cycling devices. Denaturation of double stranded nucleic acids, primer annealing, and precision control over primer extension by polymerase can be accomplished by applying stress to a nucleic acid. These methods can provide one ore more benefits over conventional PCR methods including: precision control over the PCR process; generally improved fidelity; improved accuracy over problematic sequences such as GC-rich or tandem repeat regions; greater sequence length; increased reaction yield; reduced experimental time; greater efficiency; lower cost; greater portability; and, robustness to various environmental parameters, such as temperature, pH, and ionic strengths.

    摘要: A microfluidic device for altering the flow of a carrier fluid containing a polymer, such that, the polymer can be positioned, aligned, or elongated. The device accomplishes these effects by directing the carrier fluid in a laminar flow into obstacles, or other fluids to knowingly alter the path of the carrier fluid streamlines. These streamlines, in turn, apply fluidic drag forces against the polymer to manipulate it into a desired configuration. Other aspects of the device retain a polymer in an aligned or elongated state with crimps which prevent portions of the polymer from coiling. These structures utilize the natural concept of increasing entropy to allow small portions of an aligned or elongated polymer to return to a high entropy, or coiled state, while retaining the majority of the polymer in a low entropy, aligned or elongated state for subsequent analysis or manipulation.
