    摘要: A microfluidic chip includes microfluidic channels, elements for thermally and optically isolating the microfluidic channels, and elements for enhancing the detection of optical signal emitted from the microfluidic channels. The thermal and optical isolation elements may comprise barrier channels interposed between adjacently-arranged pairs of microfluidic channels for preventing thermal and optical cross-talk between the adjacent microfluidic channels. The isolation element may alternatively comprise reflective film embedded in the microfluidic chip between the adjacent microfluidic channels. The signal enhancement elements comprise structures disposed adjacent to the microfluidic channels that reflect light passing through or emitted from the microfluidic channel in a direction toward a detector. The structures may comprise channels or a faceted surface that redirects the light by total internal reflection or reflective film material embedded in the microfluidic chip.

    摘要: The present invention, in one aspect, provides a method for calibrating thermal control elements in situ using a single compound calibrator. In some embodiments, the present invention uses a compound calibrator to calibrate thermal control elements on a microfluidic device. In non-limiting embodiment, the compound calibrator can be a droplet, plug, slug, segment or continuous flow of any appropriate solution that, when heated, yields a thermal response profile with a plurality of features (e.g., maxima, minima, inflection points, linear regions, etc.).

    摘要: The invention relates to methods and devices for control of an integrated thin-film device with a plurality of microfluidic channels. In one embodiment, a microfluidic device is provided that includes a microfluidic chip having a plurality of microfluidic channels and a plurality of multiplexed resistive thermal detectors (RTDs). Each of the RTDs is associated with one of the microfluidic channels. The RTDs are connected to a power supply through individual electrodes and pairs of common electrodes. Adjacent RTDs may be driven with alternating polarities, and the current in the common electrodes may be minimized using a virtual ground circuit. The compact microfluidic device is capable of fast heating and highly precise thermal control. The compact microfluidic device is also capable using the RTDs to sense temperature without their heating capability.
