METHOD FOR DESIGNING MICRO-CHANNEL AND SYSTEM FOR DETECTING BIO-ELEMENT USING THE SAME

摘要

The present invention provides a method for controlling the supply of the micro-fluid by a centrifugal force and capillary forces, and provides the rationale that clearly identify the capillary force acting on the micro channel can be accurately talk the design of the micro channel, after the reaction smile fluid supply flow path design method capable of rapidly removing a sample smiling remaining in the fluid supply system, and relates to a measuring system using the same biological material, ; Smile fluid supply flow path design method according to the present invention, in as has a predetermined width, height and angle design the supply flow passage of the micro fluid having an open area, the pressure (ΔPs) by capillary forces acting on the supply passage It characterized in that it is designed to be adjusted by the following equation. ; _{ΔPs = -2σ (cosθ A / h} + cosθ I / w) + 2σcosθ R (1 / h + 1 / w 0) ; (Here, w is the width of the front _passage, w 0 is the width of the rear euros, h is the height of the euro, σ is the surface tension, β is an open angle of the _euro, θ A is the contact angle with a smile fluids earlier in _euros, θ R smile at a contact angle with the fluid back _flow, θ I is for each of you to bend a critical angle of the micro-fluid front toward the open area, its value is _{θ a θ I θ a} + β. Further, _θ a + β is the maximum 180 °.) ; Cantilever, smile fluid, valves, centrifugal force, capillary
