Abstract
A microfluidic device includes a channel through which a reaction solution flows. The channel passes through a reaction section having a plurality of temperature zones set at predetermined different temperatures. The channel includes, at least in the reaction section, a region where a cross-sectional area decreases in a feeding direction of the reaction solution.
Claims15
A microfluidic device comprising:
- a channel through which a reaction solution flows, the channel passing through a reaction section having a plurality of temperature zones set at predetermined different temperatures,
- wherein an effective cross-sectional area of the channel across the entirety of the reaction section gradually decreases in a feeding direction of the reaction solution.
A microfluidic device comprising:
- a channel through which a reaction solution flows, the channel passing through a reaction section having a plurality of temperature zones set at predetermined different temperatures, wherein
- an effective cross-sectional area of the channel in the reaction section gradually decreases in a feeding direction of the reaction solution such that the cross-sectional area of the channel in the reaction section maintains the reaction solution at a constant velocity as the reaction solution passes through each of the plurality of temperature zones of the reaction section,
- the effective cross-sectional area of the channel in the reaction section decreases in a step-wise fashion in the feeding direction of the reaction solution,
- the reaction section includes a plurality of lines comprising sections of the channel having different orientations with respect to each other that are arranged in a meandering fashion though the plurality of temperature zones, and
- the effective cross-sectional area of the channel in the reaction section decreases in the step-wise fashion with each line in the feeding direction.
