Description
本發明係關於一種微型混合器之結構，詳言之，係關於一種內含複數個菱形流道及至少一檔板之微型混合器之結構。The present invention relates to the construction of a micromixer, and more particularly to a structure of a micromixer containing a plurality of diamond shaped flow passages and at least one baffle.
微流體晶片中，檢體和試劑混合是最關鍵的程序。巨觀世界中，利用紊流(Turbulent flow)混合流體是常見的方式。但在微尺度系統中，流體要達到紊流混合是困難且不實際的，所以許多不同的流體混合方法正廣泛的被研究開發。而微型混合器發展至今，依其混合機制大致可分為兩類：主動式混合與被動式混合。主動式混合器除了驅動流體所需能量，尚須提供額外的能量、機械元件等外力使流體形成混合；被動式混合器主要利用流道設計達到流體間的對流與擴散作用達到混合效果。In microfluidic wafers, sample and reagent mixing is the most critical procedure. In the giant world, it is a common way to mix fluids with Turbulent flow. However, in microscale systems, it is difficult and impractical for fluids to achieve turbulent mixing, so many different fluid mixing methods are being researched and developed extensively. Since the development of micro-mixers, they can be roughly divided into two categories according to their mixing mechanism: active mixing and passive mixing. In addition to the energy required to drive the fluid, the active mixer must provide additional energy, mechanical components and other external forces to mix the fluid; the passive mixer mainly uses the flow channel design to achieve the convection and diffusion between the fluids to achieve the mixing effect.
一般將被動式混合器分成兩類，一為利用流體之間的擴散達到完全混合，另一為利用三維之流道設計促使流體產生渾沌流達到混合。J.Branebjerg等人製作立體結構之微型混合器，其概念是以上下左右相互之交叉流道，使得欲混合之流體有更多的接觸面積來增加混合效果，如[J.Branebjerg,P.Gravesen,J.P.Krog,and C.R.Nielsen,"Fast mixing by nomination," IEEE,pp.441－446,1996.]所揭示。S.C.Jacobson等人利用多分支之管道結構，使流體不斷經由十字交錯的管道來增進接觸面積，達到可混合多種不同比例與成分之混合流體，如[S.C.Jacobson,T.E.McKnight,and J.M.Ramsey,"Microfluidic devices for electrokinetically driven parallel and serial mixing," Analytical Chemistry,Vol.71,pp.4455－4459,1999.]所揭示。此方式需要長時間長混合長度達到流體混合。Passive mixers are generally divided into two categories, one to achieve complete mixing by diffusion between fluids, and the other to utilize three-dimensional flow path design to promote fluid flow to achieve mixing. J. Branebjerg et al. make a micro-mixer with a three-dimensional structure, the concept of which is the cross-flow path between the upper and lower sides, so that the fluid to be mixed has more contact area to increase the mixing effect, such as [J.Branebjerg, P.Gravesen , JPKrog, and CRNielsen, "Fast mixing by nomination," IEEE, pp. 441-446, 1996.]. SCJacobson et al. utilize a multi-branched tube structure to allow fluids to continuously increase the contact area via cross-staggered tubes to a mixture of fluids of various ratios and compositions, such as [SCJacobson, TEMcKnight, and JMRamsey, "Microfluidic Devices for electrokinetically driven parallel and serial mixing, "Analytical Chemistry, Vol. 71, pp. 4545-4459, 1999." This method requires a long mixing length to achieve fluid mixing.
此外，尚有一些學者利用渾沌流現象增進混合。A.D.Stroock等人在流道中製作出規則排列之魚脊凹槽，如[A.D.Stroock,S.K.W.Dertinger,A.Ajdari,I.Mezic,H.A.Stone and G.M.Whitesides,"Chaotic mixer for microchannels," Science,Vol.295,pp.647－651,2002.]所揭示。當液體通過此凹槽結構，會產生三維旋轉渦流(Spiral recirculation)，使流體產生三維螺旋運動達到混合。此缺點為凹槽內之流體流動性不佳，容易產生靜滯區(Dead Zone)。In addition, some scholars have used the phenomenon of chaotic flow to enhance mixing. ADStroock et al. created regularly arranged fish ridge grooves in the flow channel, such as [ADStroock, SKWDertinger, A. Ajdari, I. Mezic, HAStone and GM Whitesides, "Chaotic mixer for microchannels," Science, Vol. 295, pp. 647-651, 2002.]. When the liquid passes through the groove structure, a three-dimensional spiral vortex is generated, which causes the fluid to generate a three-dimensional spiral motion to achieve mixing. This disadvantage is that the fluid in the groove is not fluid, and it is easy to generate a dead zone.
產生渾沌流之三維度流道設計普遍存在製程繁瑣，整合度低等缺點。快速混合之研究中，M.Engler等人是以T型流道作為混合器，並且利用數值模擬分析在不同流速下，微流體在T型流道處的流場改變，根據其流場狀態而定義三種不同的機制，以利後者對於T型流道混合器之研究，如[M.Engler,N.Kockmann,T.Kiefer,and P.Woias,"Numerical and experimental investigations on liquid mixing in static micromixers," Chemical Engineering Journal,vol.101,pp.315－322,2004.]所揭示。S.H.Wong等人探討深寬比與雷諾數對於T型流道混合器之影響，並以矽晶圓為基材與玻璃做接合增加其微型混合器之強度，如[S.H.Wong,M.C.L.Ward,and C.W.Wharton,"Micro T－mixer as a rapid mixing micromixer," Sensor and Actuator B：Chemical,vol.100,pp.359－379,2004.]所揭示。上述設計中，流體在雷諾數500以上會有不錯的混合效果，雷諾數500以下之應用將受限。另一缺點為需提供極高之驅動能量。The three-dimensional flow channel design that produces the chaotic flow has the disadvantages of cumbersome process and low integration. In the rapid mixing study, M. Engler et al. used a T-flow channel as a mixer and used numerical simulation to analyze the flow field of the microfluid at the T-flow channel at different flow rates, depending on the flow field state. Three different mechanisms are defined to facilitate the latter's research on T-flow channel mixers, such as [M. Engler, N. Kockmann, T. Kiefer, and P. Woias, "Numerical and experimental investigations on liquid mixing in static micromixers, "Chemical Engineering Journal, vol. 101, pp. 315-322, 2004.]. SHWong et al. explored the effect of aspect ratio and Reynolds number on the T-type flow channel mixer, and joined the glass with a silicon wafer as the substrate to increase the strength of the micro-mixer, such as [SHWong, MCLWard, and CWWharton, "Micro T-mixer as a rapid mixing micromixer," Sensor and Actuator B: Chemical, vol. 100, pp. 359-379, 2004. In the above design, the fluid will have a good mixing effect above the Reynolds number of 500, and the application of the Reynolds number below 500 will be limited. Another disadvantage is the need to provide extremely high drive energy.
因此，有必要提供一種創新、簡單且具進步性的微型混合器，以解決上述問題。Therefore, it is necessary to provide an innovative, simple and progressive micro-mixer to solve the above problems.
