| 摘要 |
A lab-on-a-chip (LOC) device for detecting pathogens in a biological sample, the LOC device having an inlet for receiving the sample, a supporting substrate, a first dialysis section for separating pathogens from larger constituents in the sample, a lysis section downstream of the dialysis section for lysing the pathogens to release genetic material therein, the lysis section having a lysis chamber and a heater for lysing the pathogens while the sample is in the lysis chamber, a nucleic acid amplification section downstream of the lysis section for amplifying nucleic acid sequences in the genetic material, and, a second dialysis section downstream of the nucleic acid amplification section for prehybridization filtration of amplicon produced by the nucleic acid amplification section, the second dialysis section being configured to remove cell debris from the amplicon, wherein, the first dialysis section, the lysis section, the nucleic acid amplification section and the second dialysis section are all supported on the supporting substrate.
