Molecular biological fluid detection method and a detection device

The present invention discloses a molecular biological fluid detection device, comprising a first substrate and a second substrate, the first substrate comprises a plurality of samples through-holes with a diameter different from each other at least in part with the sample through hole, said plurality of sampling a through hole for screening a biological fluid of a polymer, a second substrate stacked on top of the first substrate and comprising a plurality of tubes for a position corresponding to the vertical tube and the sampling probe through the hole, the detecting tube for detecting the corresponding sample of the polymer having a through-hole whether, and generates a detection output signal. The present invention also provides a method of detecting biological fluid molecular sieve. Molecular biological fluid sensing device according to the present invention, the first substrate as a fluid having a high molecular sieves, the detector array as a second substrate, the high integration molecular biological fluid detection apparatus, simple processing, the molecular sieve biological fluid detection methods facilitate the application.
