基于亲液和/或疏液的微阵列实现流量控制的微流控芯片
摘要：
本实用新型提供了一种基于亲液和/或疏液的微阵列实现流量控制的微流控芯片，涉及即时检测产品技术领域。该微流控芯片使用流量控制器控制微流道内液体的流速，流量控制器包括由若干阵列单元排布而成的微阵列；阵列单元为设置于微流道表面的具有形状的疏液层或亲液层；其中，若流量控制器为减速流量控制器则包括由若干疏液阵列单元排布而成的微阵列，疏液阵列单元的接触角大于微流道；若流量控制器为加速流量控制器则包括由若干亲液阵列单元排布而成的微阵列，亲液阵列单元的接触角小于微流道。该微流控芯片采用阵列单元排列而成的微阵列来控制微流道内液体的流动速度，具有成本低廉、制备简单、无需外部驱动等优势。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model provides a microfluidic chip for realizing flow control based on lyophilic and/or lyophobic microarrays, and relates to the technical field of instant detection products. According to the micro-fluidic chip, a flow controller is used for controlling the flow velocity of liquid in a micro-channel, and the flow controller comprises a micro-array formed by arranging a plurality of array units; the array unit is a lyophobic layer or a lyophilic layer which is arranged on the surface of the micro-channel and has a shape; wherein if the flow controller is a deceleration flow controller, the flow controller comprises a microarray formed by arranging a plurality of lyophobic array units, and the contact angle of the lyophobic array units is larger than that of the microchannel; and if the flow controller is an accelerated flow controller, the flow controller comprises a microarray formed by arranging a plurality of lyophilic array units, and the contact angle of the lyophilicarray units is smaller than that of the microchannel. The micro-fluidic chip adopts the micro-array formed by arranging the array units to control the flowing speed of the liquid in the micro-channel, and has the advantages of low cost, simplicity in preparation, no need of external driving and the like.
