  • Patent number: 11396020
    Abstract: In one aspect, the present disclosure provides an integrated microfluidic device for nucleic acid amplification and microarray detection. In one aspect, the device comprises: (1) a microchip configured to process reagents, comprising a plurality of reservoirs, channels, valves, and/or fluid interfaces; (2) an amplification chamber for PCR, carried out in a detachable tube assembled on the microchip through a joint; and (3) a microarray chamber comprising a microarray and a reaction chamber. In some embodiments, these features are interconnected to allow transportation of reagents for nucleic acid amplification and hybridization detection functions in a closed system. In one aspect, the integrate device herein overcomes the problem of contamination during the amplification and hybridization reactions.
