Abstract:
A DNA capillary comprising:at least one tubular fluid passageway for a liquid defined by a wall for transmitting light in at least a part thereof, said tubular fluid passageway extending straight on the substrate in a longitudinal direction, the cross sectional area of said tubular fluid passageway along a plane perpendicular to a fluid flowing direction being constant over the entire length of a processing region of said tubular fluid passageway, the processing region of said tubular fluid passageway producing a capillary function, said tubular fluid passageway being bent and tapered at least partially to prevent bubble generation in the liquid; and a plurality of different kinds of DNA probes formed in an inner wall of said tubular fluid passageway, said DNA probes being immobilized in a ring-like manner to make one complete rotation along the inner wall of said tubular fluid passageway in a predetermined amount for each kind of DNA probe and independently from each other depending on the kind of DNA probe.
