Since conventional DNA sequence analyzing technologies are based on the fundamental principle of fluorescent detection, expensive, complex optical systems and laser sources have been necessary.A field-effect device for gene detection of the present invention analyzes a base sequence by immobilizing a single-strand nucleic acid probe at a gate portion, inducing hybridization at the gate portion to form a double-stranded DNA, inducing elongation reaction by adding a DNA polymerase and one of the substrates, and measuring the electrical characteristic of the field-effect device caused by elongation reaction.Since the elongation reaction of one base induced at the gate portion can be directly converted to an electrical signal, expensive lasers or complex optical systems are not needed. Thus, a small gene polymorphism detection system that can conduct measurement at high precision can be provided.

A microfluidic device comprises a matrix of rotary flow reactors. The microfluidic matrix device offers a solution to the “world-to-chip” interface problem by accomplishing two important goals simultaneously: an economy of scale in reagent consumption is achieved, while simultaneously minimizing pipetting steps. N2 independent assays can be performed with only 2N+1 pipetting steps, using a single aliquot of enzyme amortized over all reactors. The chip reduces labor relative to conventional fluid handling techniques by using an order of magnitude less pipetting steps, and reduces cost by consuming two to three orders of magnitude less reagents per reaction. A PCR format has immediate applications in medical diagnosis and gene testing. Beyond PCR, the microfluidic matrix chip provides a universal and flexible platform for biological and chemical assays requiring parsimonious use of precious reagents and highly automated processing.
