    Abstract: A microfluidic chip for a microfluidic system includes a micro-to-macro seal. The microfluidic chip has a substrate, at least one microfluidic pathway in the substrate, and a PDMS seal layer on the substrate and above the microfluidic pathway. The PDMS seal layer provides a seal above the microfluidic pathway and prevent particles or contaminants entering the micro-channel during transportation or prior to application. During application, a needle or piping pierces through the PDMS seal layer, and fluid can be pumped into the microfluidic chip without concern for the fluid leaking despite high pressure required to pump or drive the fluid into the microfluidic pathway.

    Abstract translation: 用于微流体系统的微流控芯片包括微到宏密封。 微流控芯片具有底物,底物中的至少一个微流体途径,以及基底上的PDMS密封层和微流体途径之上的PDMS密封层。 PDMS密封层在微流体通道之上提供密封,并防止在运输过程中或施用前颗粒或污染物进入微通道。 在施加期间,针或管道穿透PDMS密封层,并且尽管泵送或驱动流体进入微流体通路所需的高压力,但流体可被泵送到微流体芯片中,而不用担心流体泄漏。
