    摘要： A system is provided for carrying out real time fluorescence-based measurements of nucleic acid amplification products. In a preferred embodiment of the invention, an excitation beam is focused into a reaction mixture through a surface, the reaction mixture containing (i) a first fluorescent indicator capable of generating a first fluorescent signal whose intensity is proportional to the amount of an amplification product in the volume of the reaction mixture illuminated by the excitation beam and (ii) a second fluorescent indicator homogeneously distributed throughout the reaction mixture capable of generating a second fluorescent signal proportional to the volume of reaction mixture illuminated by the excitation beam. Preferably, the excitation beam is focused into the reaction mixture by a lens through a portion of a wall of a closed reaction chamber containing the reaction mixture. The same lens is used to collect the first and second fluorescent signals generated by the first and second fluorescent indicators, respectively, in response to the excitation beam. The ratio of the fluorescent intensities of the first and second fluorescent signals provides a stable quantitative indicator of the amount of amplification product synthesized in the course of the amplification reaction.

    摘要： Apparatus are disclosed that thermally cycles samples between at least two temperatures. These apparatus operate by impinging fluid jets onto the outer walls of a sample containing region. Because the impinging fluid jets provide a high heat transfer coefficient between the jet and the sample containing region, the sample containing regions are uniformly cycled between the two temperatures. The heat exchange rate between the jets and the sample regions are substantially uniform.

    摘要： Microfluidic assemblies, systems, and methods are provided for manipulating fluid samples. Assemblies include an elastically deformable cover layer and a less elastically deformable substrate. The methods include deforming the substrate through the cover layer so that when the cover layer rebounds a new communication results in the assembly between the cover layer and the substrate and/or so that a new barrier wall is formed. Systems for carrying out the methods are also provided.
