摘要
A lab-on-a-chip (LOC) device for pathogen detection, genetic analysis and proteomic analysis of a biological sample, the LOC device having an inlet for receiving the sample, a supporting substrate, a leukocyte dialysis section for dividing the sample into a leukocyte stream, and a pathogen and erythrocyte stream containing cells and sample constituents smaller than a first size threshold, a pathogen dialysis section for dividing the pathogen and erythrocyte stream into an erythrocyte stream and a pathogen stream containing cells and sample constituents smaller than a second size threshold, a leukocyte lysis section downstream of the leukocyte dialysis section for lysing the leukocytes with a lysis reagent to release genetic material and proteins therein, a leukocyte incubation section downstream of the leukocyte lysis section for enzymatic reaction of the genetic material with enzymes, a leukocyte nucleic acid amplification section downstream of the leukocyte incubation section for amplifying nucleic acid sequences, a pathogen lysis section downstream of the pathogen dialysis section for lysing the pathogens with a lysis reagent to release genetic material and proteins therein, a pathogen incubation section downstream of the pathogen lysis section for enzymatic reaction of the genetic material with enzymes, a pathogen nucleic acid amplification section downstream of the pathogen incubation section for amplifying nucleic acid sequences, an erythrocyte lysis section downstream of the pathogen dialysis section for lysing the erythrocytes with a lysis reagent to release proteins therein, wherein, the leukocyte dialysis section, the pathogen dialysis section, the leukocyte lysis section, the pathogen lysis section, the erythrocyte lysis section, the leukocyte incubation section, the pathogen incubation section, the leukocyte nucleic acid amplification section and the pathogen nucleic acid amplification section are all supported on the supporting substrate.
